The New Westminster Police Department will investigate a Vancouver police officer who pushed a disabled woman to the ground while walking on East Hastings Street earlier this month.

New Westminster police will assume both the criminal and the Police Act investigations into the incident, the Vancouver Police Department (VPD) said Tuesday in a news release.

The department will investigate the constable who pushed a woman with cerebral palsy to the ground, as well as two other constables who were with him at the time.

The officer has been reassigned and is no longer walking the Hastings St. beat, the VPD said.

A surveillance video showing the pushing incident was released last week by the B.C. Civil Liberties Association. It showed footage taken at the beginning of July on a sidewalk near the crowded United We Can recycling centre on East Hastings St.

On the video, the woman, who gave her name as Sandy and did not want her last name to be used, appears to brush past an officer who is walking with two others.

The officer shoves her to the ground, and he and the other officers stand over her before walking away, leaving her lying on the ground.

The woman told CBC News she was just trying to get past the three officers on the busy street and asked them several times to let her through.

The police publicly apologized for the incident and said at the time that an internal investigation was underway.
