The video pretty much shows it all.
York Regional Police are looking for the guy seen in the security camera footage, cold cocking a woman in the face... twice.
Now, police are hoping you may know who this man is.
The story starts in a bar in Richmond Hill back in April, when two groups started to fight inside the establishment on East Beaver Creek and Highway 7.
That altercation spilled out onto the sidewalk, where one of the men hits a woman in the face hard enough he knocked her down, with her face slamming into the ground. Police say soon after, he did it again.
He then took off.
The suspect has been described as male, South Asian, 25 to 30 years old, medium build, black hair and was wearing a blue Adidas jacket at the time.
The 22-year-old woman who was hit, suffered serious injuries.
