The SIU said the charges wererelated to a police operation in December 2011 near Ontario Street and Gerrard Street East.

"Plainclothes officers entered a second floor apartment in a residence, and there was an interaction between an officer and [Liboth] Bangala," the SIU said in a news release.

As a result of the altercation the 27-year-old Bangala "sustained a gunshot wound."
