The brother of the alleged captor of British model Chloe Ayling has been arrested, police have said.
Michal Konrad Herba, 36, was arrested at an address in the Tividale, West Midlands, on 16 August.
He is the brother of suspect Lukasz Pawel Herba, who is being held by Italian police after Ms Ayling was allegedly kidnapped in Milan.
Ms Ayling, 20, was allegedly held by a group called Black Death for five days.
Michal Herba was arrested in a joint operation by West Midlands Police and East Midlands Special Operations Unit (EMSOU) and is due to appear at Westminster Magistrates Court on 17 August.
It is alleged the kidnappers attempted to sell Ms Ayling online for £230,000.
Italian police said she was attacked by two men, drugged with ketamine and abducted, apparently to be sold in an online auction.
