A mentally ill Iraqi man who beat a fellow detainee to death at an immigration facility is due to be sentenced.

Zana Yusif, 32, killed frail Bangladeshi national Tarek Chowdhury in a cell at Colnbrook Immigration Removal Centre on December 1 last year.

Mr Chowdhury, 64, was taken to hospital following the violent attack at the centre and was pronounced dead.

Yusif is due to be sentenced by the Common Sergeant Richard Marks at the Old Bailey on Monday.

He previously pleaded guilty to manslaughter by diminished responsibility.
