Three Mississauga teens — including a 14-year-old boy — are facing robbery charges after a knife was used to threaten a young man outside City Hall.

The 24-year-old Mississauga man wasn’t injured when a group of teens approached him armed with a knife at City Centre and Living Arts drives Thursday (May 3) about 10 p.m.

Peel Const. Iryna Yashnyk described the incident as a “robbery with a knife” in which a smartphone was taken.

A heavy and quick police response resulted in three people being arrested.
