MARKHAM, Ont. — Police allege a Chinese national studying in Canada was shocked multiple times by a man with a stun gun in a violent kidnapping that took place in the underground parking garage of his condominium north of Toronto.

York regional police say Wanzhen Lu, 22, was walking with his friend at about 6 p.m. on Saturday toward the elevator when he was ambushed by a group of men who attacked and then dragged him into the van in Markham, Ont.

Const. Andy Pattenden says the four suspects were in a black Dodge Caravan with stickers indicating that it is wheelchair accessible.

Pattenden says police aren’t sure which direction the van fled once it left the parking garage.

He says the woman who was with Lu wasn’t injured, but has been traumatized by the incident.

Pattenden says officers are concerned for Lu’s safety and want the public to call police or 911 if they see the van or if they have information.
