Police have released surveillance video footage of a violent attack that took place in the city's Entertainment District in hopes of identifying the suspects.

The brutal attack took place in the early hours of March 30. Police say a large group of men approached several people waiting in line to buy hot dogs from a street vendor in the John Street and Front Street West area at approximately 3 a.m.

There was a verbal confrontation between the two groups and the suspects began "kicking and punching the young people, causing serious injuries," police said in a statement Wednesday morning.

Graeme Halliday was one of the people who were attacked. He says the fight started after his friend told the suspects to wait in line.

"My friend said, 'You got to wait in line, get in the back of the line,' and that's when he went nuts," Halliday told CTV Toronto on Wednesday. "They were about four guys who jumped on me and about four guys on all my friends….They fractured my face."

Police said a person attempted to stop the fight, but was also attacked.

"For his efforts, that Good Samaritan was also beaten and chased way," Det. Jason Shankaran said. "In fact, one of the suspects was overheard telling him that 'if you try and help the person on the ground, we will kill you.'"

Police said the suspects, all in their early 20s, fled in various directions after the fight. They are described as having an olive complexion. One of the suspects was wearing a white shirt and pants and had a faux-hawk hairstyle. He was driving a white, four-door 2004- to 2008 Mercedes CLS.

Anyone with information is asked to contact police at 416-808-5200, Crime Stoppers at 416-222-TIPS (8477).
