WINNIPEG -- A body that reviews serious matters involving police is looking into complaints from two people who say they were injured during arrests by Winnipeg officers.

The Independent Investigation Unit of Manitoba says the first complainant says his arm was injured while he was being handcuffed on Feb. 7.

He says he went to hospital after his release and was told his arm was sprained or dislocated.

The man says he has been off work since then.

The second complainant says he required surgery after his hand was injured during an arrest on Oct. 4.
