Toronto police say they have arrested a male after a shooting left a teen boy dead in Scarborough on Monday afternoon.

The shooting happened in the area of Markham and Ellesmere roads. A caller told police that gunfire was heard at about 3:10 p.m.

When police arrived at the scene, they found the teen suffering from a gunshot wound. He was rushed to a trauma centre and died in hospital later.

Duty Insp. Susan Gomes, spokesperson for the Toronto Police Service, told reporters near the intersection that officers arrested the male within 20 minutes of finding the victim. He has not yet been charged.

The names and ages of the suspect and victim have not been released.

Gomes said she could not say if the suspect and victim knew each other or if there was an altercation prior to the shooting.

Police have spoken to witnesses, but are continuing to search for security camera video.

The police's canine unit was out searching for clues. Police helicopters also circled the area.

Next of kin is being notified.

Homicide detectives have taken over the investigation.

Woburn Collegiate Institute, which is nearby, was locked down shortly after dismissal as officers investigated the shooting, but the lockdown has since been lifted.
