Riot police who pushed an elderly protester in Buffalo, USA, have been charged with assault, Reuters reports.

The charges against police officers Aaron Torgalski, 39, and Robert McCabe, 32, follow a worldwide video in which they are seen pushing 75-year-old activist Martin Gugino.

In the video, one riot-equipped cop would push Gugino with a bar and the other with his hand. As a result, the man fell backwards and hit his head on the street, after which he was left lying on the ground bleeding.

Gugino is still in a critically injured state. New York Governor Andrew Cuomo said he spoke to the man on Friday, and this is Cuomo saying he is recovering from his injuries.

Torgalski and McCabe have both denied guilt. According to police, the fall of Gugino was due to his stumbling. The trial will take place in July - if the men are found guilty, they could face up to seven years in prison.

Police had already been shelved from their posts as a result of the incident. On Thursday, Reuters said 57 Buffalo riot police resigned from their unit in protest of the shelving of their colleagues.

A representative of the local police organization has described “the police only did their job”.
