Witnesses spotted the suspect approaching Wellington Market on Wellington Road with a knife in his pocket and trying to put on a black cloth mask around 7:30 p.m. Tuesday.

The suspect was described as a black male about 30 years old, six feet tall, and wearing a black sweatshirt with a gold tribal design, police said. He had covered his face with a white cloth.
