Police are stepping up patrols in a Letchworth street after windows have been smashed in repeated acts of vandalism.

Stones have been thrown on four separate occasions at homes in Waysbrook, where a number of elderly people live.

A house was targeted on Saturday at 10.40pm, following similar incidents – two of which resulted in smashed windows – which took place at night on May 3, April 26 and 30.

North Herts Community Safety Sgt Richard Wilmot, said: “What might seem like a prank and funny to some is actually mindless vandalism which is causing some elderly residents who live in the area a great deal of distress.

“Coupled with this, residents are also having to go through the inconvenience and expense of replacing broken windows.

“We are determined to stop this behaviour and find out who is responsible so they can be dealt with appropriately. To tackle these incidents, CCTV is being installed and we will be increasing our patrols around the area.

“I would urge anyone who knows who may be responsible for this irresponsible behaviour to please get in touch as soon as possible.”

Anyone with information is asked to contact police on 101 quoting crime reference number G2/15/792.
