A series of visits by suspected bogus callers may be linked, police have warned.

Two flats were targeted in Tonbridge, with cash stolen from one, and men claiming to be water board officials turned up at the home of a women in her 80s in the Sevenoaks area.

A police spokesman said: “We is remind residents of some crime prevention advice following reports of suspected rogue traders posing as engineers from the water board in Sevenoaks and Tonbridge.“

Three men are reported to have visited a property in Delagarde Road, Westerham, at 2.05pm last Friday.

They told the occupant, a woman in her 80s, that they needed to turn her water off due to a flood and were let in.

One of the men then turned off the supply while another appeared to conduct a brief search of the property.

Police say that no items were stolen however the circumstances are believed to be suspicious.

Officers have also not ruled out the possibility this may be linked to reports that two flats were targeted in Waterloo Road, Tonbridge.

This was seven days before during the late morning and early afternoon.

A quantity of cash is reported to have been taken from one home.

To guard against such callers police advise people to lock their back doors and windows before answering the front door.

Never leave your front door unattended. If you need to get something, close it until you return.

Use a spyhole and ask who the caller is through the door first, then keep the door on the chain.
