The video, posted to YouTube Jan. 2, depicts an officer speaking in French to a panhandler dressed in baggy shorts and a T-shirt on a day when temperatures sank to 22 degrees below zero, about complaints police received from four people about the man's aggressive behavior while asking for change, the Canadian Broadcasting Corp. reported Friday.
The officer told the man to find a place to warm up and calm down, and then told him he would tie him to a pole for an hour if he did not calm down.
"We have been made aware of the video, remarks are unacceptable, we're following up. Commander of the neighborhood police station will meet with the officer in the next few hours," Montreal police tweeted.
Mayor Denis Coderre condemned the officer's actions.
"The police officer's remarks are unacceptable. Commander is taking necessary measures. Am concerned about the homeless man's condition," he tweeted.
