The alleged assailants attacked a 27-year-old man at a shopping plaza on the Mountain near Upper Gage Avenue and Lincoln Alexander Parkway on Feb. 4 in broad daylight, according to investigators.
The attack was random and involved three males and one person waiting in a car.
The incident, captured on surveillance video, showed the three suspects chasing the victim and knocking him to the ground. One of the three also sprayed an unknown “irritant” similar to bear spray at the alleged target.
The three attackers then fled the scene in a dark-coloured sedan believed to be a 2010 four-door black Ford Fusion with winter tires on the front and regular tires on the rear, says police.
The victim received treatment for minor injuries from the fall and from the irritant that was sprayed.
All four of the males arrested are facing an assault charge, with an 18-year-old from Hamilton facing multiple charges and a 22-year-old also facing charges for not complying with his probation.
Two of the accused are male youths who can not be identified due to the youth criminal justice act.
The vehicle the attackers escaped in, has been recovered.
