The police say they are looking for a suspect after a surveillance video shows a man carrying a woman to her car and driving off in Richmond Hill.
The York Regional Police said the woman rang the door on Saturday at about 2.50 am at a home in High Tech Road and Silver Linden Drive.
The police said the door was not answered, but video surveillance shows a man who seems to be armed with a gun coming out of a parked vehicle and an argument with the woman on the porch of the house.
Researchers said the video shows that the man, who wore a hoodie, drags the woman to his car by her hair and drives off, threatening to kill her.
The police appeal to everyone who knows that the suspect or the woman immediately contacts the researchers.
Const. Andy Pattenden told Global News on Thursday that there is no known connection between the homeowners, the victim and the suspect. He said it is unclear why the woman went home.

Pattenden said that researchers are "very concerned" for the safety and welfare of the victim.
They also urge companies in the neighborhood or houses with video surveillance or drivers who are close by with dashcam images to come forward.
Anyone with information is asked to contact the regional police of York at 1-866-876-5423, ext.7241 or call Crime Stoppers at 1-800-222-8477.
