People have been warned not to approach a "dangerous" prisoner who has absconded while on licence.
Wayne Harris, 41, was serving an eight-year sentence for offences including false imprisonment and serious violence.
He was jailed at Snaresbrook Crown Court in December 2007.
The Metropolitan Police said Harris had failed to return to his bail accommodation in Newham, east London, on Monday.
Anyone who sees Harris has been told to contact the police immediately.
