A British model who was kidnapped in Milan and detained for six days while her captor tried to auction her online has reportedly returned to the UK.
The 20-year-old woman, named in reports as Chloe Ayling, was attacked on July 11 by two men as she attended an arranged photo shoot.
She is believed to have been drugged and transported in a bag to Borgial, an isolated village near Turin, before being released on July 17, Italian Police said.
Ms Ayling has now flown back to the UK and returned to her home in Coulsdon, south London, according to reports.
Speaking on her doorstep she told how she had feared for her life throughout the "terrifying experience".
A Polish man, who lives in Britain, was arrested on July 18 on suspicion of kidnap and extortion, state police said.
Officials have released a mugshot of the suspect, named as 30-year-old Lukasz Pawel Herba.
It is alleged two men tried to sell Ms Ayling online for more than 300,000 dollars (£230,000) and demanded the model's agent pay to secure her safe release.
She was kept handcuffed to furniture but was freed after six days and taken to the British consulate in Milan, despite the ransom not being paid.
It has been reported the captor demanded £50,000 upon her release and threatened to kill her if she told police about the incident.
Milan police officer Lorenzo Bucossi told reporters the group the suspect was allegedly working for offered "mercenary services" on the dark web.
According to a translation on Sky News, Mr Bucossi said: "Certainly the author of this very serious crime is a dangerous person, don't forget he was also ready to carry out a 'final solution', as he called it.
"He was a killer and was working for an organisation on the deep web that is offering mercenary services such as bombing attacks, kidnapping and the selling of girls on the dark web."
Italian police said they are working with officials in Britain and Poland as they continue to investigate.
A spokeswoman for West Midlands Police said an address in Sampson Close in Oldbury was raided on July 18 in connection with the investigation.
A National Crime Agency (NCA) spokesman said: "The NCA and the East Midlands Special Operations Unit have been providing support to the Italian authorities during this investigation."
He added: "The NCA has participated in both domestic and international investigations against dark web sites and shown that we have the capability and determination to bring offenders to justice regardless of how secure they feel hiding behind technology."
