After Andishae Akhavan asks why he was arrested, the arresting officer suddenly punches him.
The West Vancouver Police Department will investigate the circumstances around an arrest in which a Vancouver police officer punched a suspect.
The Office of The Police Complaints Commissioner ordered the West Vancouver department to step in after video of the arrest spread across the Internet.
The video shows Constable Ismail Bhabha punching a man he was attempting to put into handcuffs during an arrest in Vancouver on March 25.
The officers involved said they were trying to arrest Kharazi Akhavan because he rode his bicycle through a red light and wasn't wearing a helmet.
The complaint commissioner's office has determined it's in the public interest to investigate the allegations against the officer.
The office said it learned of the incident through the media, and when the office contacted the Vancouver Police professional standards department, it didn't know about the punch either.
