An urgent hunt for two men who have absconded from hospital in south-west London has been launched by the Metropolitan Police.
Adil Maxamed, 20, and Ramon Martin, 31, absconded from Springfield Hospital at around 22:10 BST on Friday with one other man, the force said.
The pair were patients at the psychiatric hospital under the Mental Health Act.
They were last seen boarding a Northern line train at Tooting Bec station at 22:35 BST on Friday and the public has been warned not to approach them.
The force said that the movements of Mr Maxamed and Mr Martin are of urgent interest.
It is not known whether the two escapees have remained together.
Mr Maxamed has links to Kingston and Mr Martin has links to Battersea, police added.
A spokesperson for the Met Police said that the men absconded from the hospital in Glenburnie Road after breaking a glass door.
Officers detained one man at around 00:45 BST on Saturday at a residential address in south London and returned him to the hospital.
Mr Martin sustained injuries to his arm while breaking the glass door, which require medical attention, the force added.
Anyone who has seen either of the men has been asked to call 101 and quote the reference 8713/19jul.
The public was urged to call 999 immediately if the men are sighted.
