A violent home invasion in Alexandra Park has prompted police to issue an arrest warrant for a 20-year-old man.

Back in July, police say a man followed a 26-year-old woman into her apartment building at 170 Vanauley Walk, located just south of Dundas Street West and Kensington Market.

Police say the man then forced his way into the woman's apartment, put her in a headlock and held a knife to her neck.

He then threatened her and ransacked her home, according to police.

Investigators are now looking for Robert Vanderveer, 20.

He is described as 6'5 tall, 180 pounds with red hair brown eyes and facial hair.

He is considered violent and anyone who sees him is being told not to approach him and call 911 instead.
