Two Polish brothers worked together to mastermind the plot to kidnap Coulsdon model Chloe Ayling, a court has heard.

Lukasz Herba, 30, and his 36-year-old brother Michal Herba, are alleged to have been part of a group calling itself Black Death, which is active on the dark web.

Ms Ayling, 20, is believed to have been snatched by the gang after being lured to a fake modelling shoot in Italy last month.

Lukasz Herba is currently in custody in Italy, having been arrested after delivering Ms Ayling to the British embassy on July 17 - six days after she was allegedly kidnapped. He has said he did not knowingly take part in any crime.

On Wednesday, the National Crime Agency (NCA) arrested Michal Herba in the Tividale area of Sandwell in the West Midlands.

Michal Herba was apprehended on a European Arrest Warrant issued by the Italian authorities. Westminster Magistrates' Court heard on Thursday that he would contest extradition.

Ms Ayling, 20, was allegedly drugged and bundled into the boot of a car after being tricked into attending the bogus photoshoot in Milan on July 11.

The Italian police claim the two brothers are part of Black Death. Black Death say they sell women as sex slaves online to buyers in the Middle East.

Ms Ayling says she was injected with the horse tranquilliser ketamine, handcuffed and gagged before being stuffed in a suitcase by her kidnappers.

She says she was then driven 120 miles to an isolated farmhouse in the village of Borgial in the commune of Lemie outside of Turin.

In a series of television appearances, she described being forced to lie on the floor with her hands and feet handcuffed to the legs of a chest of draws.

But she was freed after six days and driven to the British consulate in Milan on July by Lukasz Herba, where he was arrested.

Doubts have been cast on her account after it emerged she went shopping with one of her captors and made no attempt to escape.

She insists that she was in fear for her life.
