Special Police Sergeant Chris Pope was deliberately hit with a Quad bike on Alfred Rose park on Saturday Night.
He is currently recovering in Stoke Mandeville Hospital after both bones were broken in his leg.
Sources have told the Bucks Herald that Thames Valley police have arrested a suspect.
Special Sergeant Pope made an emergency call for assistance after the incident, with a full response from the MPAS Helicopter, Road Units and Dogs dispatched to the popular park to apprehend the subject.
Special constables are volunteer police officers who have exactly the same powers as a regular officer, and (with minor exceptions) wear the same uniform and are issued the same equipment. The roles of "specials" can vary greatly from force to force, though normally include working with local regular officers to provide an additional and heightened police presence on the streets and in the local community. They may also be requested to police particular events such as football matches and community events.
