Counter-terrorism police investigating a "large scale" alleged fraud linked to extremists travelling to Syria have arrested seven people.
Six men and one woman have been arrested after raids on seven addresses in London and Luton as part of a probe into allegations that vulnerable and elderly victims are 'cold-called' by someone impersonating a police officer and scammed out of money.
The men, all in their 20s and 30s, were arrested on suspicion of conspiracy to commit fraud and money laundering and a 32-year-old woman was arrested on suspicion of money laundering.
A 46-year-old woman was also arrested during a property search in north London on suspicion of a separate offence under the Child Abduction Act in relation to a young girl travelling to Turkey whose whereabouts remain unknown.
She has been bailed until June alongside two women, aged 20 and 21, who were previously arrested in relation to this inquiry.
