The advice comes after bogus officials struck in the High Street, Tean, on Monday 19 September.
It is believed two men were working together and used a water-related rouse to trick their way into the home of an elderly lady. It is not known if the offenders had access to a vehicle.
At approximately 6pm one of the men called at the home of the 91-year-old and claimed to be in the area ‘doing the drains’. He entered the house and asked her to run the tap and flush the toilet to make sure the water was running clear.
Whilst the lady was distracted it is believed the second man has entered the house and stole a small amount of cash and documents.
The second man was not seen but the first is described as white, aged 40 to 50, with dark brown hair worn in a side parting. He was approximately 6ft and well built. He was softly spoken and polite. He wore dark casual clothing and did not have any identification.
An investigation into the incident is now underway by detectives, who are pursuing a number of lines of inquiry including extensive house-to-house enquiries and gathering CCTV footage from the locality.
Officers want to speak to anyone with information, or who saw suspicious persons and/or vehicles in the area prior to the incident.
Residents are encouraged to contact police if and every time they have suspicions about any caller at their door.
Even if someone claims to be an official - and that includes police officers and council representatives - people must get their ID checked out.
Residents are asked to remain vigilant at all times and to follow this advice:
Never trust anyone calling at the door without a prior appointment. Should you receive such a call leave the door locked. The caller will hear you through the door when you ask them who they are. If they state they are from a utilities company ask for your account number, they should have this, if not, do not let them in and tell them to leave, and that you are calling the Police.
Always ask for ID, and check it.
Do not allow anyone to carry work out on your home, or sell you anything when they cold call at the door. If you do require work to be done, INSTIGATE IT YOURSELF, by phoning three companies asking for like for like quotes. Then decide.
Do not keep large amounts of cash in your home, you may think that you have the perfect hiding place, but these criminals will find it.
Please remember there is no such company as the Water Board, Gas Board or Electric Board. These words are only used by offenders.
Always report any suspicious behaviour to the police, if you think it is suspicious, it probably is.
Keep your doors locked even when you are home.
Residents should also follow the stop, chain and check rule when people call at the door:
STOP - If you are not expecting anybody and they don’t have an appointment - don’t let them in
CHAIN - Use your door chain or bar before opening the door
CHECK - Ask to see ID and double check this.
People can also use the Nominate a Neighbour (NAN) scheme which diverts cold callers to a neighbour who will check caller’s identity. NAN packs are available from local police stations.
