Four arrested by Metropolitan Police over trafficking of women
Four men have been arrested on suspicion of trafficking women into the UK to be sexually exploited.
The Metropolitan Police said inquiries suggested that a criminal network had trafficked hundreds of women into the country from Europe.
Most of the women were from Hungary, the force spokesman said.
Raids were carried out on addresses in Camden, Tower Hamlets, Barnet, Haringey, Enfield and Luton earlier.
Two of the searched addresses were believed to be operating as brothels, and potential trafficking victims were found at some of them, a spokesman for the Met's Trafficking and Prostitution Unit said.
They were taken to a specialist agency for support, he said.
It was believed that many of the women were told they would be given jobs as receptionists, but were forced into prostitution, the spokesman added.
Computers, cash and travel documents were seized by officers.
A 33-year-old British man from Barnet, north London, two Hungarian men aged 32 and 31, and a third Hungarian man, of an unknown age, are in custody at a police station in north-west London.
