Toronto police have arrested a third Brampton teenager in connection with a series of carjackings and an armed robbery of a retail store last June.

Police allege the teens committed four carjacking robberies across the GTA between June 7 and June 15. In each carjacking, two of the accused approached the victim and forcefully took their car keys before stealing the vehicle, police allege.

In one of the incidents, one of the teens allegedly used a “Taser-style” weapon on the victim, police said in a news release issued on Tuesday, Jan. 7.

On June 17, police allege the suspects robbed a store in the area of Eglinton Avenue West and Dufferin Street of cash and cellphones.
