An off-duty policeman was stabbed with a large kitchen knife while trying to stop moped thieves from robbing a man.
The City of London officer remains in a stable condition on Sunday evening following the incident in Lewisham, south east London, on Saturday.
A Metropolitan Police spokesman said the victim continued to try and stop the robbery, despite being hit with a ‘large kitchen knife’. The suspects later made off without the moped.
Scotland Yard said the officer, 37, quickly intervened when he saw a group of four males on mopeds attempting to steal another moped from a 21-year-old man at Maylons Road.
The spokesman said: ‘During the confrontation the officer was stabbed in the leg, but despite this, he continued to confront the four suspects thwarting the theft of the moped until the suspects fled the scene.
‘The officer was taken to a south London hospital where his injuries were described as not life-threatening or life-changing.’
The 21-year-old victim of the attempted theft was also assaulted by suspects and suffered bruising.
Anyone with information is asked to contact police on 101.
