Police have released an image of two key witnesses they are searching for in relation to a murder at a south east London train station.
Sam Winter was taken to hospital in critical condition after he was assaulted on the stairs of Southwark Underground Station at around 9.30pm on August 22.
The 28-year-old died in hospital two days later on the evening of August 24.
Months later, police are continuing to investigate the murder and are hoping to identify two people who may have critical information which could help the investigation.
Despite extensive enquiries, officers have so far been unable to identify them.
Rakeem Miles of East Street, Southwark was initially charged with grievous bodily harm with intent.
Following the victim’s death, it was amended to murder.
Investigating officer, Detective Sergeant Tony Gittins said: “We are releasing these images of two people thought to be witnesses in a murder investigation.
“I would like to stress these people are not suspected of any criminal activity, but they may have important information that will help our investigation.
“If this is you, or you know anyone pictured, please text 61016 or call 0800 40 50 40 quoting reference 772 of 22 August."
