TORONTO, July 14: Police on Wednesday arrested three teenagers who had allegedly stabbed to death a Pakistani student in the heart of Mississauga city, 26 kilometres west of Toronto.

Mohammed Sohail Mushtaq, 19, a high school student, who immigrated with his family from Saudi Arabia a few years ago, was attacked with knives by four youngsters in the parking lot of Square One, police said.

Sohail was rushed to nearby Trillium Health Centre, where he was pronounced dead. A spokesman for the Mississauga police said the motive behind the killing of Sohail was not known yet.

However, he said police were looking for a fourth suspect in this homicide. Sohail's father, Malik Mushtaq, a Canadian of Pakistani origin, has recently set up a travel agency in Mississauga. Sohail, who was raised in Jeddah, was intending to study in University of Toronto, family sources said.
