A Chinese student who was kidnapped in Canada on Saturday has been found alive, turning up at the door of a home in a small town located almost 200 kilometers away from where he was last seen.

22-year-old Lu Wanzhen was forced into a van by three masked men inside of an underground parking garage in the city of Markham, located just north of Toronto, at shortly before 6 pm on Saturday. According to police who viewed the surveillance tape, the kidnappers ambushed Lu as he got out of a vehicle with a female friend and used a stun gun multiple times to subdue him before dragging him off.

Investigators have not yet revealed how Lu then ended up at the quiet cottage town of Gravenhurst, Ontario, where he knocked on the door of one home asking for help at just before 9 pm on Tuesday night. The homeowner quickly called the police who showed up to take Lu to a nearby hospital where he was found to have sustained some minor injuries.

Police are still searching for the four individuals who abducted Lu. The black Dodge Caravan that they used was found in Toronto on Monday and is now being combed through in search of clues. One suspect, a 35-year-old man from Toronto, was arrested on Tuesday but was released unconditionally without charge later in the day.

While police have yet to detail why Lu was targeted, they have confirmed that the student drove a number of luxury cars, including a Lamborghini, Rolls Royce, and Range Rover. It was Range Rover that he stepped out of shortly before being kidnapped.
