OPINION OF THE COURT
Aрpellant Melvin Douglas Brown was indicted on charges of murder and voluntary manslaughter arising out of the October 13, 1973 killing of Mary Lee Walters. Appellant’s pre-trial application to suppress was denied and the case proceeded to trial on June 18, 1974. The jury found appellant guilty of murder of the second degree. Post-verdict motions were denied, and appellant was sentenced to ten to twenty years imprisonment. In this appeal, 1 appellant contends that the court erred in denying his application to suppress incriminating statements taken from him by the police. We agree, reverse judgment of sentence, and remand for a new trial. 2
*566 I
When ruling on suppression motions, the suppression court is required to make findings of fact and conclusions of law as to whether evidence was obtained in violation of the defendant’s constitutional rights. Pa.R.Crim.P. 323 (i). The suppression court must determine whether the Commonwealth has established by a preponderance of the evidence that the challenged evidence is admissible. See Pa.R.Crim.P. 323(h). On review, our responsibility is “to determine whether the record supports the factual findings of the court below and the legitimacy of the inferences and legal conclusions drawn from those findings.”
Commonwealth v. Goodwin,
If the suppression court has determined that the evidence is admissible, “this Court will consider only the evidence of the prosecution’s witnesses and so much of the evidence for the defense as, fairly read in the context of the record as a whole, remains uncontradicted.”
Commonwealth v. Kichline,
Applying these standards the evidence establishes the following: On Saturday, October 13, 1973, the victim was stabbed to death while working after-hours in an of *567 fice on the twenty-third floor of the Koppers Building, a downtown Pittsburgh office building. Her body was discovered at about 2:00 a.m., the next morning.
On Sunday, October 14, the Pittsburgh Police Department interviewed individuals who had been in the building the night before. Two detectives went to the home of appellant, a security guard who had been on duty in the Koppers Building the night of the killing. They arrived at appellant’s home at 11:00 a.m. They requested appellant to accompany them to the Public Safety Building for questioning. Appellant complied and was taken to the Public Safety Building.
Appellant arrived at the Public Safety Building at noon. Appellant was taken to an interview room where he was left for approximately an hour. The room had no windows, and the door was left closed. The two detectives returned to the interview room at 1:00 p.m., Sunday. Appellant was not advised of his constitutional rights before questioning but was told he was not under arrest. The two detectives asked him about his work schedule at the Koppers Building the night before. The detective who testified at the suppression hearing could not remember if appellant was asked if he was involved in the killing.
Appellant was questioned intermittently all afternoon. Other members of the Koppers Building staff were аlso questioned at the Public Safety Building Sunday afternoon.
At approximately 9:00 p.m., appellant agreed to take a polygraph examination. The polygraph operator, who had been called in earlier that day, examined two individuals : appellant and James Robinson, a security guard who had been on duty with appellant the night of the killing. Appellant was given Miranda warnings 3 in con *568 nection with the polygraph examination. The examination began with background questions, including questions relating to appellant’s work schedule the night of the killing. Appellant was also asked if he had been on the twenty-third floor that night, and if he knew who might have committed the killing. Appellant was then asked ten specific questions relating to the crime.
After the polygraph examination, appellant was asked to consent to the search of his home. He was informed orally of his right to refuse to consent to the search and signed a consent form. The consent form included a statement that appellant understood he was not in custody.
Appellant was then driven back to his home by the two detectives who picked him up that morning. They arrived at appellant’s home at 10:30 p. m. After appellant gave thе officers the clothes he had been wearing on the night of the killing, they drove him back to the Koppers Building, where appellant completed the balance of his 4:00 p. m. to midnight shift.
The next afternoon, Monday October 15, appellant attended a meeting of security guards called by Koppers Building officials. Police officers were present and took handwriting samples, hair samples, and photographs of the security personnel. Lieutenant James Pampeña, who was in command of the police investigation, interviewed Robinson and appellant at the Koppers Building. After noting certain discrepancies between Robinson’s and appellant’s stories, Pampeña requested that appellant accompany him and three other officers to the Public Safety Building to “iron out” the discrepancies. Robinson was also taken to the Public Safety Building.
They arrived at the Public Safety Building at approximately 5:15 p. m. Pampeña first questioned Robinson for about five minutes, then began interrogation of appellant. During this session, appellant made statements which conflicted with statements he made earlier that *569 afternoon. At 7:35 p. m., Pampeña confrontеd appellant with these discrepancies and gave appellant Miranda warnings. Appellant subsequently admitted he killed the victim. He agreed to have his statement recorded on tape and, after being given a second set of Miranda warnings, repeated his admission on tape. Appellant was arraigned at about 10:00 p. m., Monday, October 15.
II
Appellant contends he was subjected to custоdial interrogation without being informed of his rights, requiring suppression of his oral admission and the taped statement which followed. We agree. 4
Miranda v. Arizona,
As this Court stated in
Commonwealth v. O’Shea,
“ 'whether the suspect is physically deprived of his freedom in any significant way or is placed in a situation in which he reasonably believes that his freedom оf action of movement is restricted by such interrogation ..’ Commonwealth v. Romberger, [454 Pa. 279 , 283,312 A.2d 353 , 355 (1973), vacated,417 U.S. 964 ,94 S.Ct. 3166 ,41 L.Ed.2d 1136 (1974), reinstated on remand,464 Pa. 488 ,347 A.2d 460 (1975)], citing Commonwealth v. Marabel [445 Pa. 435 , 441,283 A.2d 285 , 288 (1971)].”
Accord,
Commonwealth v. Fisher,
Applying this standard, and considering the effect of аppellant’s contact with the police on both Sunday and Monday, we conclude that appellant reasonably believed his freedom of action was restricted when he was taken to the Public Safety Building on the second day of interrogation, Monday, October 15. Thus, the subsequent questioning constituted a custodial interrogation, for which prior warnings were required.
On Sunday, October 14, the police took appellant to the Public Safety Building, and questioned him intermittent *571 ly over a ten hour period. Appellant was not brought back home until the police wanted to pick up his clothing.
The following afternoon, Monday October 15, Lieutenant Pampeña questioned appellant at the Koppers Building about his activities the night of the killing. After this additional questioning, Pampeña informed appellant that there were discrepancies between his statements and those made by the other security guard on duty with him the night of the killing. Pampeña requested that appellant return to the Public Safety Building for further interrogation. Appellant was escorted to the Public Safety Building by Pampeña and three other officers and placed in an interview room. While appellant was told he was not undеr arrest when he was picked up the day before, there is nothing in the record to indicate that appellant was told he was not under arrest when he was brought to the Public Safety Building on Monday. Nor does the record reveal any indication that appellant was told he was free to leave. Questioning began five minutes after appellant arrived at the Public Safety Building, but no warnings were given until twо hours later.
In
Commonwealth v. Romberger,
“After four hours of interrogation at the police station, appellant could not reasonably have believed that his freedom remained unfettered. . . . [A] reasonable man in appellаnt’s situation would have clearly perceived the restraint on his freedom.”
Id. at 283,
Additionally, when appellant returned to the Public Safety Building on Monday, he knew that the police did not merely want information they had not asked for earlier. Rather, appellant must reasonably have understood that the discrepancies between his statements and those of the other security guard had aroused suspicions in the police that the police wished to explore through further interrogation. The questioning was moved from appellant’s place of work to the police station, and appellant was told the further interrogation at the police station would be necessary to iron out discrepancies between his story and statements given by the other security guard. Considering all the circumstances known to appellant, we must concludе that appellant could not reasonably have believed that his freedom remained unfettered when he was taken to the Public Safety Building Monday evening. Therefore, warnings were required. 6
*573
In
Commonwealth v. Banks,
In ruling on appellant’s application to suppress, the suppression court simply concluded that appellant’s admission was voluntarily given, without addressing the issue of when custodial intеrrogation began. On
*574
post-verdict motions, the court reasoned that warnings were not required when interrogation began at the Public Safety Building because appellant was not the focus of the police investigation, as both he and the other security guard had been taken to the Public Safety Building. However, in
Commonwealth v. Simala,
“ ‘[Wjhenever an individual is questioned while in custody or while the object of an investigation of which he is the focus, before any questioning begins the individual must be given the warnings established in Miranda . '
Id. at 225,
*575 We also conclude that the failure to warn appellant of his rights before interrogation began at the Public Safety Building Monday evening requires the suppression of the oral admissions and the subsequent taped statement obtained later that evening. These admissions were obtained through exploitation of the statements obtained from appellant during the earlier, pre-warning interrogation.
At the suppression hearing, Lieutenant Pampeña testified that he confronted appellant with the discrepancies between statements he made that evening at the Public Safety Building and the statements he made earlier that afternoon at the Koppers Building, and that this led to appellant’s admission. Appellant repeated his admission on tape shortly thereafter. Because appellant’s admissions were obtained through exploitation of statements taken before appellant was warned of his rights, they must be suppressed. See
Commonwealth v. Banks,
Because the court failed to suppress the incriminating statements taken from appellant in violation of his constitutional rights, appellant is entitled to a new trial.
Judgment of sentence reversed and a new trial granted.
Notes
. We hear this appeal pursuant to the Appellate Court Jurisdiction Act of 1970, Act of July 31, 1970, P.L. 673, art. II, § 202(1), 17 P.S. § 211.202(1) (Supp.1977).
. A review of the record convinces us appellant’s claim that the evidence is insufficient to sustain a verdict of murder of the second degree is without merit. See Act of December 6, 1972, P.L. 1482, § 1, formerly codified at 18 Pa.C.S.A. § 2502(b) (1973). In view of our disрosition of this case, we need not address appellant’s other assignments of error: (1) denial of a challenge to the *566 array of the petit jury; (2) denial of a motion for a continuance until a new jury selection law came into effect; (3) restriction of questioning of prospective jurors on their attitudes about psychiatric testimony; (4) denial of a challenge for cause of а prospective juror; (5) denial of an application to suppress clothing taken from appellant; (6) admission of evidence of a vaginal bruise on the victim; (7) denial of four requested jury instructions; and (8) the trial court’s summarization of a witness’ testimony.
. See
Miranda
v.
Arizona,
. Because we conclude that these statements must be suppressed for failure to warn appellant of his constitutional rights, we need not address the other grounds asserted for suppression of these statements: that they were (1) involuntary; (2) the product of an unnecessary delay between arrest and arraignment; and (3) the product of an unlawful arrest, made without probable cause.
. The accused must be informed that he has the right to remain silent, that anything he says can be used against him in court, that he has the right to consult an attorney and to have an attorney present during any questioning, and that an attorney will be provided for him if he cannot afford one.
Commonwealth
v.
Leaming,
. Both the Sunday and Monday interrogations of appellant are in marked contrast to the interrogation in
Oregon
v.
Mathiason,
Thus, the mere fact that appellant, like Mathiason, was told he was not under arrest does not mean that appellant was never subjected to custodial interrogation. Whatever effect being told he was not under arrest had on the Sunday interrogation, it certainly had no affect when appellant was brought to the police station again on Monday. Nor can we conclude that the questioning of appellant was not сustodial interrogation simply be *573 cause the police requested that appellant come to the Public Safety Building. See Graham, What is “Custodial Interrogation?”: California’s Anticipatory Application of Miranda v. Arizona, 14 U.C.L.A.Rev. 59, 79-80 (1966).
. The Commonwealth does not contend that the
Miranda
warnings given to appellant on Sunday night, in connection with the polygraph examination, satisfy the requirement that he be given warnings before being interrogated at the Public Safety Building on Mondаy. The
Miranda
warnings were given twenty hours earlier, by a different police officer. See
Commonwealth
v.
