Four people have been arrested after a collision on Highway 404 involving a vehicle that was used to flee a jewelry store robbery at a Newmarket mall on Wednesday afternoon.

York Regional Police (YRP) said a call came in shortly before 5:30 p.m. for a commercial robbery at Upper Canada Mall.

Five suspects entered a jewelry store and stole unknown quantities of merchandise, YRP said. During the robbery, two people were pepper-sprayed.

The suspects drove away but YRP said they followed the vehicle to Highway 404 near Steeles Avenue East.

Officers subsequently took four suspects into custody. Police said a fifth suspect remains outstanding.
