    (a-3) Any peace officer employed by a law enforcement agency of this State may conduct temporary questioning pursuant to Section 107-14 of this Code and may make arrests in any jurisdiction within this State: (1) if the officer is engaged in the investigation of criminal activity that occurred in the officer's primary jurisdiction and the temporary questioning or arrest relates to, arises from, or is conducted pursuant to that investigation; or (2) if the officer, while on duty as a peace officer, becomes personally aware of the immediate commission of a felony or misdemeanor violation of the laws of this State; or (3) if the officer, while on duty as a peace officer, is requested by an appropriate State or local law enforcement official to render aid or assistance to the requesting law enforcement agency that is outside the officer's primary jurisdiction; or (4) in accordance with Section 2605-580 of the Illinois State Police Law of the Civil Administrative Code of Illinois.

    (c) If an arrest is made in this State by a peace officer of another State in accordance with the provisions of this Section he shall without unnecessary delay take the person arrested before the circuit court of the county in which the arrest was made. Such court shall conduct a hearing for the purpose of determining the lawfulness of the arrest.
