A warning message to local Neighbourhood Watch members says this happened sometime between 8pm on Saturday August 29 and 11am on Sunday August 30, with the offenders causing extensive damage to the vehicles.
This comes after a similar incident in which criminal damage was caused to a blue Renault Clio in the car park of Llangollen Youth Club in nearby Willow Street the previous weekend.
A warning from Neighbourhood Watch, highlighted by llanblogger last Saturday, said this incident is thought to have taken place between 5.30 and 11.23pm on Sunday August 23 with what is believed to have been a sharp implement being used to smash all the windows of the vehicle.
