An ambulance with a patient on board was attacked in Donaghamede, Dublin last night.
Dublin Fire Brigade said crew members were assaulted by a man who climbed into the ambulance and tried to remove the patient.
The windows were smashed and the ambulance had to be taken out of service.
A fire engine from the ambulance crew’s station came to assist after the incident on Carndonagh Road, but its crew was also attacked.
