A video posted on the popular website Youtube has helped Canadian police find a man they believe responsible for a murder.
Police in the Southern Ontario city of Hamilton said that they uploaded a one-minute, 12-second clip from a surveillance tape onto the video-sharing site.
The video, which showed suspects arriving at a local nightclub for a Sean Price hip-hop concert, garnered media attention and was viewed more than 30,000 times.
George Gallow (24), of Hamilton, who is seen in the clip wearing a baseball cap with the word "Joker" on the front, turned himself into police on Tuesday and has been charged with second degree murder and attempted murder.
He is accused of stabbing Ryan Milner (22) and his friend in a car park after the November concert.
Milner died shortly after being stabbed in the chest. His friend is still recovering.
