Appellant contends that: 1) the evidence was insufficient to prove that he did not withdraw from the alleged conspiracy; 2) his arraignment on closed circuit television violated his constitutional rights to a fair arraignment and a fair trial; 3) amendment of the indictment against him to include the name of a coconspirator was improper and prejudicial; 4) the suppression court erred in failing to suppress an inculpatory statement allegedly the product of unnecessary delay between arrest and arraignment; and 5) the suppression court erred in failing to suppress the statement allegedly the fruit of arrests and a search made without probable cause. We disagree and, accordingly, affirm. 1
On December 6, 1977, a court sitting without jury convicted appellant of recklessly endangering another person, criminal conspiracy, possession of an instrument of crime, risking catastrophe, arson-endangering persons and arson-endangering property. After denying post-verdict motions, the court sentenced appellant to concurrent terms of imprisonment of one to three years on the charge of criminal conspiracy, one to three years on the charge of possession of an instrument of crime, two to six years on the charge of risking catastrophe, three to twelve years on the charge of arson-endangering persons and one and one half years to four years on the charge of arson-endangering property.
On the evening of November 27, 1976, appellant attended a party at the home of Marc Shambor. Around 1:00 A.M. the following morning, appellant and several others from the party went to a nearby bar, where they engaged in a fight with a group of blacks. Police Officer William Murtha *516 arrived to quell the disturbance and heard appellant shout that he was going to “get” the blacks that night. Appellant and his comrades returned to Shambor’s home, where he, Shambor and two others filled four beer bottles with gasoline and inserted a rag wick in the top of each bottle. The four discussed going to the Hillside Apartments, 3901 Manayunk Avenue, Philadelphia, where, they believed, blacks lived. Each carried a bottle to the apartments and lined up in front of one of the buildings. At least one of the group ignited the contents of his bottle and threw it at their target, causing a fire which destroyed two apartments and extensively damaged four others.
About 5:45 A.M., Officer Murtha, after hearing a report of the firebombing, spotted appellant and another white male in the vicinity of the apartments. He stopped appellant, who appeared out of breath, and decided to take him to the police station. The police obtained his name, address and similar information. At approximately 10:00 A.M., Detective Craig Sterling informed appellant of his Miranda rights and questioned him for about 30 minutes. Appellant denied any involvement in the incident. The police moved appellant to another building, where he waited for about 90 minutes for his father. His father arrived around 4:00 P.M. and took him home.
The next day, November 29, the police received information implicating appellant in the firebombing. About midnight, they filed a complaint before a magistrate, who issued a warrant to arrest appellant. Carrying the warrant, several officers arrived at appellant’s home at about 12:45 A.M., November 30. They knocked, introduced themselves and announced the purpose of their trip to a woman who answered and identified herself as appellant’s mother. The woman permitted the officers to enter and stated that she needed to go upstairs to see if appellant were home. She was gone for five to ten minutes. During that time, the officers heard noises and saw shadows indicating that more than one person was upstairs. The woman returned with a man, who identified himself as appellant’s father, and as *517 sured the officers that appellant was not home. The officers, however, searched the house and discovered appellant hiding in the closet of one of the bedrooms upstairs. They placed him under arrest at about 1:10 A.M.
Appellant arrived at the police station at about 1:50 A.M. after administrative processing, Detective John Mozzachio informed appellant of his Miranda rights at approximately 2:15 A.M. Appellant immediately began to give an oral inculpatory statement. The statement was completed and reduced to writing about 3:00 A.M. In this statement, which the Commonwealth, over objection, introduced at trial, appellant admitted participation in the events leading to the firebombing but asserted that he only “dropped” his bottle in shrubbery and ran away.
Around 3:30 A.M., the officers took appellant to the scene of the crime and conducted an hour long search for the bottle he said he had thrown away. The officers did not locate the bottle and returned with appellant to the station around 5:00 A.M. They did not question appellant further and had him arraigned sometime after 9:00 A.M., after approximately eight hours of custody. The arraigning court conducted the procedure on closed circuit television.
Appellant first argues that there was insufficient evidence to convict him on each of the charges because he withdrew from the conspiracy before the contemplated acts occurred. He testified that, although he helped to fill the bottles with gasoline and, along with each of the three others, carried a bottle to the Hillside Apartments, he wanted only to “scare” the people who lived there. He also testified that he had announced his withdrawal, thrown his bottle away and run off before the attack began. One of the other participants also testified that appellant had shouted that he was “not going through with it.” Another participant, however, testified that, although next to appellant, he had not heard his announcement of withdrawal. Moreover, when the police searched the area on November 30, they failed to discover the bottle. Further, in his statement, appellant did not mention his alleged declaration of withdrawal. Indeed, in *518 this statement, he stated that he discarded his bottle only after one of the others had thrown a bottle at the building. Appellant also testified that he had gone to the apartments “to burn something,” and that he had walked ahead of the others, leading the way.
Appellant clearly did not end his participation in the conspiracy “before the commission of the crime [became] so imminent that avoidance [was] out of the question.”
Commonwealth
v.
Roux,
Appellant contends that his arraignment deprived him of constitutional rights because it was performed on closed circuit television. Without offering specific allegátions of prejudice, he argues that this procedure created “a circus type of behavior” and denied him a fair arraignment.
Appellant’s arraignment differed from a traditional arraignment only in that the court communicated with him by way of closed circuit television. The arraignment was no more open to the public than would have been arraignment in person and created no extra publicity. The Rules of Criminal Procedure demonstrate that reliance upon mechanical and electronic devices in pretrial proceedings can be salutary and are permissible so long as they do not impair the rights of the accused.
See
Pa.R.Crim.P. 141(c)(4) (per-
*519
milting accused to make mechanical or electronic record of preliminary hearing);
Wilson v. Blake,
Appellant argues that the court erred in permitting the Commonwealth to amend the indictment to include the name of Marc Shambor as an alleged coconspirator. Appellant baldly asserts that the amendment prevented him from preparing a full defense. The indictment originally charged appellant with conspiracy and named two others as coconspirators. Pa.R.Crim.P. 220 provides that the court may allow amendment of an indictment “provided the indictment as amended does not charge an additional or different offense.”
In
Commonwealth v. Brown,
*520
Appellant contends that his inculpatory statement was the product of unnecessary delay between arrest and arraignment in violation of Pa.R.Crim.P. 130 and
Commonwealth v. Futch,
Appellant advances the novel proposition that calculation of the period involved must include the time he was held after his first arrest. Without deciding whether a valid
Futch
claim may be based on cumulation of time during more than one detention, we believe that the circumstances of appellant’s case do not permit such cumulation. Appellant’s earlier arrest occurred two days before the second, he was questioned then for only half an hour and did not incriminate himself. In
Commonwealth v. Marabel,
Appellant asserts that each of the two arrests was without probable cause and that, therefore, his inculpatory statement after the second arrest should have been suppressed as unconstitutionally obtained. Regardless of whether the first arrest was proper, the connection between the statement and that arrest was sufficiently attenuated to dissipate any taint.
Wong Sun
v.
United States,
Nothing appellant said at his first interrogation was incriminating or necessarily impelled him to give an inculpatory statement at the second questioning or led to his second arrest. Rather, his second arrest resulted from information independently received. A different officer warned appellant of his Miranda rights, informed him that two of his coconspirators had implicated him in the crime and conducted the subsequent interview. In Commonwealth v. Marahel, supra, our Supreme Court found that an inculpatory statement given during a third session of interrogation was sufficiently removed from an illegal arrest. There the appellant at the earlier questioning did not provide incriminating information, and said nothing at the earlier session which would later have impelled him to incriminate himself, the police subsequently arrested him properly on the basis of information independent of any they learned at the previous session, there occurred at the third session a confrontation with another party who implicated the appellant, the third session occurred two days after the second, different officers questioned the appellant at the third interrogation and they informed him of his Miranda rights. Consequently, appellant’s claim that the statement was the product of the first arrest is without merit.
*522 Appellant also argues that his second arrest was without probable cause. Before arresting appellant, the police obtained an arrest warrant from a magistrate by providing information from two of appellant’s coconspirators that he had engaged in planning and executing the crime. We do not hesitate to conclude that this information supplied probable cause to believe that appellant had participated in the firebombing.
Lastly, appellant argues that his inculpatory statement should have been suppressed because the arresting officers engaged in a constitutionally prohibited entry and search of his home while attempting to execute the arrest warrant. According to appellant, the officers, without a search warrant, could not enter or search his house. Appellant’s claim requires us to determine for the first time in Pennsylvania whether officers armed with a valid warrant for arrest may enter the home of a suspect named in the warrant and conduct a search there to locate him.
In those jurisdictions which have considered the question, the prevailing rule is that a valid arrest warrant confers authority upon officers to enter a suspect’s home to execute the warrant.
See United States v. Hammond,
We think this rule sound. One the one hand, common sense dictates that law officers, in possession of a valid arrest warrant, hold authority to take reasonable steps to execute the warrant. Many decisions recognize that officers, acting under probable cause to arrest but without a search warrant may enter a residence to perform the arrest.
See, e. g., United States v. Santana,
Probable cause existed to believe that appellant was on the premises, justifying the officers’ entry of the home. The residence entered was the home of appellant, whom the police knew in fact lived there and had been there recently. The officers arrived late at night, at a time when they could reasonably believe that appellant would be present. At that time, they discovered no new information undermining the belief that appellant could be found at home.
Cf. Government of Virgin Islands v. Gereau,
*525
There also existed probable cause to search appellant’s home to execute the arrest warrant. In addition to the information available when the magistrate issued the warrant, the officers observed suspicious conduct indicating that appellant was home. Appellant’s mother was upstairs for five to ten minutes, more time, a reasonable officer could have concluded, than necessary for the simple task of verifying appellant’s presence or absence. During that time, the officers heard sounds and saw shadows suggesting movement upstairs. Upon all the information available, the officers possessed probable cause to believe that appellant was home and avoiding arrest. In those circumstances, they need not have believed the mother’s declaration that appellant was not home.
State v. Hiralez,
In summary, we find that the arresting officers had probable cause to believe that appellant was at home, could enter and search his home to execute a valid arrest warrant and conducted a proper search for appellant. 5
Judgments of sentence affirmed.
Notes
. Appellant also challenges sufficiency of the evidence to support conviction for all the charges. We find the evidence sufficient to support the verdict. See 18 Pa.C.S.A. §§ 2705 (recklessly endangering another person), 903 (conspiracy), 907(a) (possession of an instrument of crime), 3302 (risking catastrophe) and 3301 (arson) (Supp. 1978-79).
. Appellant was arrested before May 16, 1977, the effective date of

. Many cases indicate that the requirement of probable cause to believe the suspect is at home is satisfied when the police arrive at a residence they reasonably believe is that of the suspect.
See Commonwealth v. Williams,
. Nor did the search itself violate constitutional strictures. The police did not use the search as a pretext to uncover incriminating evidence or otherwise extend it beyond what was necessary to locate appellant.
