A fourth man has been arrested as part of an ongoing investigation into money laundering and fraud to fund terrorism in Syria.
On Tuesday (March 10), officers arrested a man at Heathrow Airport - shortly after he arrived from America - on suspicion of money laundering. He remained in custody at a south London police station on Tuesday afternoon.
The man, aged 28, is believed to be involved in a large-scale fraud linked with UK extremists travelling to Syria.
He was bailed on Thursday until a date in early April pending further enquiries.
The arrest comes after three others - two from west London - were arrested last Wednesday (March 4) , and later bailed , as a result of operations led by the Metropolitan Police's Counter Terrorism Command (SO15).
Police investigating the fraud said unsuspecting victims are cold-called on their home phone by someone claiming to be a police officer, telling them their bank account has been compromised. The victim is then tricked into transferring money from their account to an account under control of the fraudster, with the money then used to fund terrorism in Syria.
One elderly victim is believed to have lost approximately £150,000 as a result.
In a statement, a Metropolitan Police spokesman said: "Members of the public are strongly advised to hang up the phone if they receive a call like this from someone claiming to be a police officer.
"Wait at least five minutes to make sure the phone line has cleared, or use another phone line, before ringing the phone number on your bank card."
The Metropolitan Police have outlined a four step solution to help combat fraud:
- Banks or the police will never ask for your pin, your bank card or to withdraw money
- Never share your pin with anyone
- Never hand your bank card or any goods you have purchased as a result of a phone call to anyone who comes to your front door
- If you think you have been a victim of a scam, call police
