A man was arrested on suspicion of fraud after a couple from Copthorne were conned out of £2,000.
They were called by a man pretending to be a Metropolitan Police police officer on Monday (February 16).
He told them someone was trying to take money out of their bank account and they should withdraw £2,000 immediately.
They were told a man would arrive that evening to collect the cash.
At 6pm a man wearing a police badge arrived and they gave him the money.
The next day they became suspicious it was a fraud and called police.
Sussex Police officers were with the couple at their home in Copthorne Bank, Copthorne, on Tuesday (February 17) when they received another phone call from a man again saying he was a police officer and that he had arrested a man who had their bank card.
They told them to withdraw cash and hand it over to a courier who was on his way to their address.
A police spokesman said: “A taxi arrived and officers briefed the driver and he took them to London to the drop off address. The driver was approached by a man who asked to hand over a package. Officers then arrested an 18-year-old London man on suspicion of fraud and he remains in custody.”
Detective Inspector Andy Bennett warned: “We advise people to be on their guard against these sort of scams.
“Under no circumstances would the police or your bank act in this way.
“If you have any suspicions, please do not use the phone you have just been called on to contact the police or your bank. If possible use another phone to report your concerns or to contact a friend or relative to alert them.
“Thankfully, many of these attempts fail as alert residents are not fooled.
“However, we urge anyone reading or hearing this message to pass it on to any friends and relatives who may be unaware of this particular type of targeted fraud.
“We want to encourage everyone to continue to resist these callers, who despicably often target elderly and vulnerable people who may easily become confused.”
