Two youths are facing attempted murder charges after an attack that left a 16-year-old boy in hospital with serious injuries.

Shortly before 3:30 a.m. Thursday, two patrol officers were responding to an unrelated call when they came across a group of people gathered around a male, who was lying in the street in the 2800 block of Sixth Avenue.

The victim, a 16-year-old boy was, taken to hospital by EMS with head injuries described as serious. He remains in hospital, police said in a news release Friday.

Around 9 p.m., officers were dispatched to a suspicious person call in the area of Third Avenue and Rae Street. Police say the person matched the description of one of the suspects in the attempted murder.

Officers arrested a 16-year-old boy at a home in the 1100 block of Angus Street. The second suspect, a 17-year-old boy, was arrested a short time later.

While the canine unit was tracking the second suspect, a police dog bit a civilian who was not involved in the investigation. Police say the dog bite will be subject to a use-of-force review.

The two suspects have each been charged with attempted murder. They cannot be named under provisions of the Youth Criminal Justice Act. Both appeared in youth court Friday afternoon.
