British Transport Police have issued an appeal for anyone who recognises this man to contact them.
Detectives have issued this CCTV image of a man they would like to speak to in connection with an incident onboard a Docklands Light Railway (DLR) service between Greenwich and Cutty Sark in south London when two youths were stabbed.
The stabbing happened at about 5.20 pm on Sunday, 17 December, and resulted in both youths needing to be taken to hospital for treatment to their stab wounds. After treatment, one of the two youths had to stay in hospital to recover from his injuries.
Detectives believe the man in the image may have information that could assist them with their enquiries into the incident and would like to speak to him or anyone who thinks they recognise him.
If anyone recognises the man in the photograph, British Transport Police would like them to contact them by text on 61016 or by calling 0800 40 50 40, quoting reference 420 of 17/12/2023.
