(a) The head of any law-enforcement agency may temporarily provide assistance to another agency in enforcing the provisions of this Article if so requested in writing by the head of the other agency. The assistance may comprise allowing officers of the agency to work temporarily with officers of the other agency (including in an undercover capacity) and lending equipment and supplies. While working with another agency under the authority of this section, an officer shall have the same jurisdiction, powers, rights, privileges, and immunities (including those relating to the defense of civil actions and payment of judgments) as the officers of the requesting agency in addition to those he normally possesses. While on duty with the other agency, he shall be subject to the lawful operational commands of his superior officers in the other agency, but he shall for personnel and administrative purposes remain under the control of his own agency, including for purposes of pay. He shall furthermore be entitled to workers' compensation when acting pursuant to this section to the same extent as though he were functioning within the normal scope of his duties.
(b) As used in this section:
(1) "Head" means any director or chief officer of a law-enforcement agency, including the chief of police of a local police department and the sheriff of a county, or an officer of the agency to whom the head of the agency has delegated authority to make or grant requests under this section, but only one officer in the agency shall have this delegated authority at any time.
(2) "Law-enforcement agency" means any State or local agency, force, department, or unit responsible for enforcing criminal laws in this State, including any local police department or sheriff's department.
(c) This section in no way reduces the jurisdiction or authority of State law-enforcement officers. (1975, c. 782, s. 1; 1981, c. 93, s. 1; 1991, c. 636, s. 3.)
