A PCSO was taken to hospital after an off-road biker deliberately drove at him while he was patrolling a country park.
The officer was walking through Reddish Vale Country Park, in Stockport, when two off road bikes appeared.
One of the riders deliberately drove at him before fleeing, police said.
The PCSO suffered arm and leg injuries.
He was taken to hospital, but has since made a full recovery.
Police have launched an investigation following the incident on Tuesday, April 21 at around 12.45pm.
No arrests have been made.
Officers have released images of a man they want to speak to in connection with the incident.
Sergeant Lorna Crowe-Moore, of GMP’s Stockport district, said: “This incident happened in a country park which is currently being used by people of all ages, including families with young children, for daily exercise so it could have had devastating consequences.
“Thankfully, the PCSO was not seriously injured but we are providing them with support whilst an investigation is underway to identify the person responsible.
"This was completely unacceptable behaviour towards anyone, never mind an officer who was in the area to protect people.
“I would like to use this opportunity to appeal to anyone with information to contact us as soon as possible. We are particularly interested in hearing from anyone who can help us identify the young man in the images or has information about the bike or where it came from.”
Anyone with information should contact police on 0161 866 9746 quoting 1113 of 21/04/20 or the independent charity – Crimestoppers, anonymously, on 0800 555 111.
