A lorry driver has been treated for head and neck injuries after being struck by a stone while attempting to remove an untaxed car in Londonderry.
Paramedics were called to Westland Mews in the Bogside area at around 3.30pm after the 46-year-old driver was hit. Stones were also thrown at police and the ambulance crew.
The lorry driver, who had been assisting police in a clampdown operation which began on Monday, sustained a serious cut to his head and vertebrae injuries.
SDLP Councillor for the area Sean Carr said the man was "trying to do his duties and attacks of this nature and attacks on the emergency services, especially ambulances, cannot be tolerated".
"I would appeal for anyone with information about this to take it to the police."
Police have asked anyone who can help identify the stone throwers to contact Strand Road station on 0845 6008000, or Crimestoppers on freephone 0800 555111.
