A man who allegedly shot and killed a Toronto teenager in what investigators called an unprovoked attack has been arrested, Toronto police said Thursday.

Abdul Yeberebaba, 20, was arrested by Calgary police officers and returned to Toronto where he was charged with second-degree murder.

One week ago, Toronto police held a news conference where they named Yeberebaba a suspect in the case and issued a Canada-wide warrant for his arrest.

Police allege he shot and killed 15-year-old Jahkai Jack last June in the area of Emmett Avenue and Jane Street. 

Jack was shot following a verbal exchange at a gathering in the area. Police said he was not involved in any gangs or criminal activity.

“He was simply a young person meeting friends on a Saturday night,” said Det.-Sgt. Phillip Campbell last week.

After the shooting, Jack was taken by people at the park to a nearby health-care centre. Residents in the area said cries for help at the facility’s front door went ignored as the teen lay bleeding out.

Two other Toronto men, 19-year-old Jayden Samuel-James and 21-year-old Rajveer Gill, were arrested and charged last week with accessory after the fact to murder.

Yeberebaba is set to appear in a Toronto court on Friday morning, police said.
