The Vancouver Police Department is under investigation for an incident that occurred during a pipeline protest last week (May 22).

The interaction occurred between a woman and a member of the force outside the Opus Hotel at 322 Davie Street in the city’s downtown core, according to a May 30 media release issued by the Office of the Police Complaint Commissioner of B.C. (OPCCBC).

Prime Minister Justin Trudeau was speaking inside the building at the time and, according to CBC News, members of the Tsleil-Waututh Nation had to be removed after disturbing the event.

The protest was in opposition of the Liberal government’s purchase of the Trans Mountain pipeline and its decision to go ahead with an expansion of the pipeline.

“The incident was recorded on video and reported in the media,” the OPCCBC’s release reads. “According to the video, during the protest a woman approaches a male standing next to a uniformed Vancouver police officer. The woman in the video steps forward and appears to make contact with one of the men, the woman is pushed back and falls to the ground.

“As the video was posted on social media and reported in the news, the Police Complaint Commissioner has determined that it is in the public interest, pursuant to sec 95 of the Police Act, to disclose that an investigation has been ordered into this incident.”
