Police have urged residents to be vigilant after a person was told to test their water in a distraction burglary.

Two men, claiming to be from the water board, knocked at the victim's property in Parkland Crescent at 7.30am on Tuesday, October 9.

One man stayed outside while the other asked the victim to run a tap and keep their hand under it to test the water.

While the person was doing so, one of the men walked around the house, where it is believed he stole some items.

Anyone who may have seen any suspicious activity in the area or anyone with information should contact DC Cormac Harrison at Norwich CID on 101.
