Toronto police arrested a 14-year-old boy and continue to search for three other suspects after three pharmacies in Toronto were robbed on Friday.

Between 3 and 4 p.m., police say they responded to calls for robberies at a plaza on The West Mall south of Bloor Street West, at a store in the area of Rexdale Boulevard and Precision Road, and at another plaza on Elmhurst Drive near Islington Avenue.

“In each incident, four male suspects entered the store while concealing their identities with masks and gloves,” a police press release read. “One of the suspects was armed with a handgun and made demands for money and drugs.”

According to police, in one case a suspect assaulted a 72-year-old woman, who fell to the ground.

In each case, the suspects took cash and drugs before leaving in a dark pickup truck, which was being driven by a boy. The driver was arrested “after a brief foot pursuit.”

The 14-year-old boy, of Toronto, was charged with three counts of robbery with a weapon and three counts of conspiracy to commit an indictable offence, among other charges.

He cannot be named due to the Youth Criminal Justice Act. There are still three unidentified suspects being sought.

Anyone with information is asked to contact police at 416-808-7350 or Crime Stoppers anonymously.
