Police officers were kicked and spat at as they attempted to help an injured man during a disturbance in Nottingham.
Police say that the officers had been called to a reported disturbance in Plantagenet Street, St Anns, at 4.45pm on afternoon 3 April.
One of the officers was spat at while in the back of an ambulance, and another was spat at and kicked after the suspect arrived at hospital.
A 28-year-old man has been arrested on suspicion of assaulting an emergency worker.
Neither officer was injured in the incident.
Inspector Paul Ferguson, of Nottinghamshire Police, said: “Officers pull on their uniforms and head out on patrol every day with the same objective in mind – to protect the public from harm and return home in the same condition.
“They simply do not deserve to be assaulted and abused during the course of their duties.
“We will not tolerate this kind of behaviour against any emergency service workers and the officer in this case will be fully supported.”
