The homicide squad is investigating after a teen was gunned down at a Regent Park townhouse complex yesterday afternoon.

A distressed man, believed to be the 18-year-old victim’s father, ran out in the intersection of Dundas and River streets just after 2 p.m. and flagged down a passing police cruiser on a routine patrol of the area.

Once out of the car, the sergeant found the teen suffering from a gunshot wound on the first floor of one of the row houses.

The victim was pronounced dead at the scene.
