Kweku Adoboli, the former UBS trader convicted of fraud, was detained when he attended his weekly appointment earlier today.

Adoboli has been fighting deportation to Ghana, where he was born and left at the age of four. He has lived in the UK since he was 12.
Foreign nationals sentenced to more than four years are automatically considered for deportation.
He was released from prison in 2015 after serving four years of a seven-year sentence for a £1.4bn fraud at Swiss bank UBS.
The ex-UBS trader who served four years of a seven-year sentence for a £1.4bn fraud has made a last-ditch bid to block his deportation to Ghana, where he was born.
Kweku Adoboli is expected to be put on a charter flight late on Tuesday, his lawyer has said.
Adoboli's legal team is seeking an injunction and a judicial review of the decision, arguing his removal was not necessary to serve the public interest.
He was released in 2015.
