A community police team has been left with a clear up mission and a repair bill after three of its vehicles were damaged.
Billingham Neighbourhood Policing Team said the attack happened between 11pm yesterday and 7.20am this morning when people entered the rear yard.
A spokesman said: "Your local team will continue to provide policing cover using other resources but your help is needed.
"If any person has information as to identity of the person/s responsible then please contact your local policing team.
"All police stations are covered by CCTV.
"This forms part of the police investigation.
"These vehicles which have been taken off the road are the very vehicles your local police would use to come to your assistance.
"The public support and help is still very much needed."
Anyone with information is asked to call Cleveland Police on 101 or Crimestoppers anonymously on 0800 555 111.
