delivered the opinion of the court:
Thе trial court sustained the motion of. defendant, John O’Connor, to quash his arrest and to suppress the evidence seized as a result of his arrest. The State appeals contending that the arrest was valid. We reverse and remand.
At 1:22 a.m. on March 21, 1986, Officer Taylor of the Palos Park police department was using radar equipment to monitor the flow of traffic on Route 45 located within Palos Park. His point of observation was a parking lot located on the west side of Route 45. Although Palos Park police were responsible for north and southbound traffic control on Route 45, Officer Taylor’s vantage point was located in an unincorporated area which was the responsibility of the Cook County sheriff’s police. From his observation point Officer Taylor saw the defendant speeding southbound on Route 45 within the jurisdiction of Palos Park. Officer Taylor then drove into Palos Park, and pursuant to his direction defendant stopped his vehicle. Defendant was then arrested in Palos Park and charged with driving under the influence of alcohol, speeding and having a blood-alcohol content greater than .10.
At the hearing on the motion to quаsh and suppress, defendant elicited testimony that Officer Taylor conducted his radar surveillance from a point just across the Palos Park border. The trial court granted defendant’s motion on the ground that Officer Taylor was not within Palos Park when he observed defendant speeding and driving undеr the influence of alcohol.
The issue is whether an intraterritorial arrest is invalidated because of the arresting officer’s extraterritorial location when he observed defendant speeding and driving while intoxicated within the officer’s jurisdiction (Palos Park). The State contends that decisions upholding extraterritorial arrests establish the propriety of the instant intraterritorial arrest either because Officer Taylor properly exercised extraterritorial statutory authority conferred by sections 7 — 4—7 and 7 — 4—8 of the Illinois Municipal Code (Ill. Rev. Stat. 1985, ch. 24, pars. 7 — 4—7, 7 — 4—8) or by section 107 — 5(c) of the Code of Criminal Procedure of 1963 (Ill. Rev. Stat. 1985, ch. 38, par. 107 — 5(c)) or was authorized to make a citizen’s arrest pursuant to section 107 — 3 of the Code of Criminal Procedure (Ill. Rev. Stat. 1985, ch. 38, par. 107 — 3). For the following reasons, defendant contends that the authority cited by the State is inаpplicable to the instant arrest: sections 7 — 4—7 and 7 — 4—8 of the Illinois Municipal Code cannot sustain the arrest because Officer Taylor positioned himself in an adjoining unincorporated area rather than an adjoining municipality; section 107 — 5(c), while authorizing arrests throughout the Statе, does not support the instant arrest because Officer Taylor left his jurisdiction to set up an extraterritorial radar site without knowing whether any violations would occur; and section 107 — 3 does not authorize a citizen’s arrest because police, not private citizens, use radаr to monitor traffic.
Sections 7 — 4—7 and 7 — 4—8 of the Illinois Municipal Code provide that adjoining municipalities within a county form a police district and that the police of any municipality within the district may go throughout the district to preserve the peace and safeguard the lives, rights and prоperty of citizens. Extraterritorial arrests have been upheld pursuant to these provisions where officers while in adjoining municipalities observed the commission of offenses. (People v. Bains (1987),
Section 107 — 5(c) of the Code of Criminal Procedure, however, is broader in scope аnd provides that arrests may be made anywhere within the State. Extraterritorial arrests have been upheld pursuant to this provision where the arresting officer had probable cause to believe that defendant had committed an offense within the officer’s jurisdiction. (People v. Aldridge (1981),
Section 107 — 3 of the Code of Criminal Procedure authorizes a private citizen to make an arrest when he has reasonable grounds to believe that an offense other than an ordinance violation is being committed. Extraterritorial arrests by police- officers have been upheld as citizen’s arrests where the offense was committed in the officer’s presence. (People v. Gupton (1985),
Both sections 107 — 3 and 107 — 5(c) of the Code of Criminal Procedure have been held to authorize extraterritorial arrests, made in either an official or citizen’s capacity, where the officer observed the commission of the offense while outside of his jurisdiction. Accordingly, had the boundary line between Palos Park and the unincorporated area been the center of Route 45 and dеfendant been arrested in the unincorporated area, the extraterritorial arrest would have been sustained either in Officer Taylor’s official capacity (Aldridge,
While no Illinois cases have been found which have dealt with extraterritorial surveillance or information gathering distinct from making an extraterritorial arrest, the matter has arisen in other jurisdictions. In Phoenix v. State (Fla. 1984),
As noted in People v. Durham and Phoenix v. State, the crucial analysis to be applied to determine the propriety of a warrantless arrest is whether probable cause can be demonstrated. The pertinent inquiry then is whether probable cause can be found where the underlying facts and circumstances were observed while a police officer was outside of his jurisdiction. Probable cause for a warrantless arrest exists where the arresting officer, based on reasonable and trustworthy information, has knowledge of facts and circumstances sufficient to warrant a man of reasonable caution in believing that an offense had been committed and that defendant is the offender. (Draper v. United States (1959),
Here, so long as Officer Taylor’s opportunity to observe was unimpeded, the fact that his vantage point was extraterritorial did not diminish the accuracy or reliability of the information gathered. Stationing himself on the edge of a roadway for which he had complete patrol responsibility, even though that edge also served as a territorial boundary, was reasonable under the facts and circumstances presented here. Furthermore, as noted previously, since the information was not obtained by the assertion of Officer Taylor’s authority as a law enforcement officer, a finding of extraterritorial authority to gather evidence under sections 7 — 4—7 or 7 — 4—8 of the Illinois Municipal Code (Ill. Rev. Stat. 1985, ch. 24, pars. 7 — 4—7, 7 — 4—8) or sections 107 — 3 or 107 — 5(c) of the Code of Criminal Procedure (Ill. Rev. Stat. 1985, ch. 38, pars. 107 — 3, 107 — 5(c)) is unnecessary. Consequently, we find that the trial court’s granting defendant’s motion to quash the arrest and suppress the evidence obtained as a result of the arrest was erroneous.
In light of the foregoing, the judgment of the circuit court of Cook County is reversed, and the cause is remanded.
Reversed and remanded.
BILANDIC and SCARIANO, JJ., concur.
