A grandmother has been left with a black eye after being 'punched to the ground by a police officer'

A Greater Manchester Police officer appeared to hit Colleen Murphy, 50, during an incident captured in footage that has gone viral on social media.

The OUTLAW PROSECUTION SERVICE has reached out to for the victim to contact but is yet to hear back.

Greater Manchester Police said it is reviewing the incident after being called to a “disturbance” on Union Street at around 9pm on Saturday evening.

In the two-minute clip, police can be seen batting people away near a Sainsbury’s supermarket as they pin a man to the ground. An officer can then be heard demanding the man “stand up” before dragging him on his back across the car park by his hands. Colleen Murphy, the man’s mother, can then be seen walking over before the police officer stands up and takes a swing at her head causing her to fall backwards.

Murphy’s daughter Danielle Willisford said her mother was left with a “massive lump on her head and bruise on the side of her face” after the officer knocked her to the ground.

Greater Manchester Police said the incident has now been referred to its Professional Standards Department, adding that the team will look at the viral footage of the events and the officers’ body-worn video.

“Greater Manchester Police are aware of a video circulating online which shows an altercation between officers and a member of the public whilst a man is being arrested,” the force said.

“At the time of his arrest a crowd had gathered, and footage of the incident has been uploaded on to social media.

“The footage shows an altercation with members of the public attempting to intervene, while officers placed the man under arrest.

“The man received a fixed penalty notice for being drunk and disorderly. There were no injuries reported.”
