A manhunt is underway after a serving prisoner absconded from a mental health hospital.

Duncan Stewart has links to the Croydon area and people are warned to not approach him if they see him.

Instead they should call 999.

Alternatively anyone with information can call the police on 07785 774447 or to remain anonymous call Crimestoppers on 0800 555111.

Stewart was last seen at about 3.30pm on Wednesday as he made off on foot from Lambeth Hospital in Landor Road, Stockwell.

The 33-year-old is serving a jail sentence for robbery and he should not be approached directly.
