Police have stepped up patrols as they search for a group of vandals who damaged 20 cars in one night.
They stabbed tyres, smashed windows and dented body parts of vehicles parked in the Clayton Brook area.
The damage was done overnight between Tuesday, November 19 and Wednesday, November 20.
Three teenage boys have been arrested by police on suspicion of causing the damage.
They have all been released on bail and must return to the police station in mid-December.

patrols in the area – both uniformed patrols and plain-clothed officers have been in the area.
“The message we want to get across to the residents is to please be vigilant.
“If you see groups of youths and you feel they may be causing damage in the area, call us
Police are appealing for information about what happened and for help to identify the people responsible.

Sgt Mountain said: “We would still ask if anybody from the Clayton Brook area has witnessed these incidents, or has any knowledge of the incidents or people involved, to come forward to speak to us.
“Also, if anybody who lives in the area has their own CCTV system that might have picked up this group of youths, and that’s not already been checked by the police, we would like to hear from you.
“Local officers are determined that they will secure a conviction in relation to these matters.”
