The incident took place on Thursday night when two women claiming to be from social services called with the victim. It was only after they left he noticed a savings book had been stolen.
Councillor Paula Bradshaw said: “The public must be vigilant and take precautions to protect themselves from falling victim to this type of crime.
“If a legitimate employee of any company knocks on your door they will be only too happy to show their identification. If they can’t provide any identification you should not let them in and contact the PSNI as soon as possible.
“My thoughts are with the victim who has had his privacy invaded and I would urge anyone with information to contact the PSNI as soon as possible. Those behind this incident must be apprehended by the police and brought to justice before the courts.”
