Police are looking for a man wanted in connection with the brutal downtown attack of another man who was falsely accused of hitting his girlfriend.

Allie Chapman said her boyfriend, Lee Dacosta, was severely beaten last November after a stranger mistakenly thought he was hitting her. Chapman said Dacosta was giving her a piggy back ride after the bars had closed in the Peter Street and King Street West area before the attack. She said her feet were sore from wearing heels.

"I slipped off of him. We were laughing. He wanted to pick me up and some guy accused him of hitting me, which was completely false," Chapman told CTV Toronto. "He was just picking me up."

Chapman said the stranger then started attacking her boyfriend. The incident, which Dacosta said he can barely remember, was caught on a surveillance camera.

"I see the man kicking Lee…and how his head went back. It was horrible," Chapman said.

In the video, Dacosta appears to be punched without warning and kicked in the head. The attack left him with severe injuries, including brain and nerve damage.

"My skull was cracked. (I suffered) severe fractures, a broken orbital bone. My nose was broken in about four places. I lost a tooth and cracked about four other ones," Dacosta said.

He also lost his sense of taste and suffered permanent injuries that require reconstructive surgeries.

"I lost my palate. My teeth constantly feel like they are in a vise grip," he said. "I'm not the same person, to be honest with you. I don't feel the same."

Police say the suspect may have "took some enjoyment" out of the attack.

"At the end of that video, you do see he has a smile on his face. He took some enjoyment out of delivering that kick and he may not be aware of the injuries he caused," Det.-Sgt. Jason Shankaran said.

The suspect is seen in the surveillance footage heading to an after-hours party on King Street after the attack. Police say Chilean soccer fans had gathered there that night after a friendly match with Brazil at the Rogers Centre.

Police believe the suspect may have ties with the Chilean community and may be from Montreal because he speaks French.
