A special constable has had a leg broken during an attack in Plymouth, police have said.
The volunteer police officer was assaulted on Sunday night after being called out to reports of a man setting off fireworks in a sensory garden on The Hoe, Devon and Cornwall Police said.
The force said the male officer was punched in the face and also suffered a broken leg.
He was receiving hospital treatment for his injuries, it added.
Police said officers were still trying to track the suspect down after he fled the scene.
In a social media post on X, formerly Twitter, the force said: "Assaults on police are absolutely not acceptable."
