York police arrest 3 teens in thefts, break-ins, robbery

Three teens are facing more than 70 charges for a series of thefts and break-ins in Richmond Hill, York police say.

A 17-year-old from Richmond Hill as well as two other 17-year-olds of no fixed address have been arrested and will appear at a Newmarket youth court Tuesday.

The charges include:

- Robbery with a gun. 

- Breaking and entering.

- Possession of stolen goods.

- Wearing a disguise with intent to commit a crime.

- Failing to comply with bail conditions.

One of the alleged incidents involves an armed robbery at 1:20 a.m. Monday. Police said a male was walking alone when he was approached by a group of other young males near Carville Road and Bathurst Street.

One allegedly held a gun to the victim's head while another held a knife to his ribs. The victim's backpack was stolen but he wasn't injured, police said. 

The suspects were later arrested. The same group of teens had been arrested in May in connection with 17 thefts from vehicles and 13 break-and-enters at commercial properties, police said. All of the incidents occurred in a community in north Richmond Hill known as Oak Ridges.

The teens cannot be identified under the Youth Criminal Justice Act. Police are still searching for a fourth suspect. 

Police also said stolen property has been recovered and are asking for victims to come forward.
