Do you know this man? E-fit issued after fake police officers take £7,000 from elderly man in Boston

The incident happened on 11 October, although police have only just released details.

The money was handed over at the victim's address in Hubberts Bridge after the two offenders claimed they were from the police.

Police say the vulnerable victim,was told to withdraw money from his bank which was then handed over to an Asian male who was believed to be driving a Black Mercedes or Aldi Saloon.

More than £4,000 was handed over at around 3pm and a further £3,000 handed over at around 5 pm at the victim’s address.

One of the offenders is described as being of slim build, in his 20s and wearing casual clothing.

Anyone who recognises the e-fit or believes they have any information to assist the enquiry is urged to call police on 101.

Investigating Officer DC Marr said “Lincolnshire Police would never tell you to withdraw money from your bank or hand money over. We would never ask for your pin number or your card. These people are hugely convincing, even making sure the victim keeps a mobile phone line open so they can hear everything that is said. If you have any suspicions at all, hang up the phone and seek the advice of a friend or relative. Although this is a common technique, there are many people who are unaware of it.

"We are supporting the City of London Police campaign and urging residents to tell two other people about this method of fraud. Knowledge is power when it comes to these unscrupulous individuals who rely on peoples trust and vulnerability.”
