Toronto police have arrested a 14-year-old boy and are searching for a second teen after a series of weekend purse-snatchings near Bathurst and Front Sts.

Four women in their 20s were each approached by two suspects believed to be adult males on Sunday, police said. One was armed with a gun, according to a public safety alert issued Tuesday morning.

In one incident, a 28-year-old woman was walking along Portugal Square near Adelaide St. when two people demanded her purse. One took out a gun and shot rounds into the ground, away from the woman, and then fled, police said.

Later that evening, another woman, 20, was attacked from behind by two people and put in a choke hold. When she refused to hand over her purse, one of the assailants indicated he had a gun. The woman was then forced to the ground and dragged.

She suffered minor cuts and bruises.

Police said the minor arrested Tuesday morning faces charges of two counts of robbery in connection with purse-snatchings that occurred Sunday evening on Wellington St. W. near Spadina Ave. as well as near 350 Queens Quay W.

Officers are searching for at least one more suspect, another 14-year-old boy.

Police had reported the suspects were described as black males between the ages of 18 and 25. Each wore a hooded sweatshirt. One was described as about 5-foot-10 with a thin build and the other is about 5-foot-9 with a medium build.

Anyone with information is asked to contact police at 416-808-1400, or to call Crime Stoppers anonymously at 416-222-TIPS (8477).
