(65 ILCS 5/1-4-5) (from Ch. 24, par. 1-4-5)

Sec. 1-4-5.

In case any injury to the person or property of another is
caused by a member of the police department of a municipality having a
population of 500,000 or over, while the member is engaged in the
performance of his or her duties as a police officer,
and without the contributory
negligence of the injured person or the owner of the injured property, or
the agent or servant of the injured person or owner, the municipality in
whose behalf the member of the municipal police department is performing
his or her duties as a police officer shall indemnify
the police officer for any judgment
recovered against him or her as the result of such injury, except where
the injury results from the wilful misconduct of the police officer.
A municipality, which is not otherwise required to indemnify
pursuant to this Section, may indemnify a police officer
for any judgment recovered against him or her for injuries
sustained as a result of the police officer's performance
of his duties as a police officer.

For the purposes of this section no civilian defense worker, nor any
member of any agency engaged in any civilian defense activity, performing
services as a part of any civilian defense program, shall be considered to
be a member of a municipal police department.

If any person in obeying the command of any such police officer to assist in
arresting or securing an offender is killed or injured or his or her
property or that of his or her employer is damaged and such death, injury
or damage arises out of and in the course of aiding such police officer in
arresting or endeavoring to arrest a person or retaking or endeavoring to
retake a person who has escaped from legal custody, the person or employer
so injured or whose property is so damaged or the personal representatives
of the person so killed shall have a cause of action to recover the amount
of such damage or injury against the municipal corporation by which such
police officer is employed at the time such command is obeyed.
