A man fatally stabbed in the chest in Kingston has been pictured for the first time.
Kai Davis, 22, from Hounslow was found dying from his wounds after police were called to reports of a disturbance in Clarence Street at 3.45pm on Saturday.
He was taken to hospital by the London Ambulance Service where he was later pronounced dead.
Police have urged witnesses to the attack to come forward with a large number of people believed to be present at the scene.
A post-mortem examination held on Monday found his cause of death to have been a stab wound to the chest.
An 18-year-old man who was arrested on suspicion of murder has now been released with no further action.
A second man, aged 19, was arrested on suspicion of murder.
He was taken to a south London police station and he was subsequently released on bail to return on a date in mid-September.
DCI Kate Kieran, leading the murder probe, said: “A dedicated team of detectives is working on this investigation. These arrests have marked significant progress and we remain committed to bringing justice to Kai’s family. I can’t imagine how difficult this time must be for them and I thank them for their continued support as we progress all lines of enquiry.
“The Met is committed to tackling violence across London, but we cannot do it alone. I continue to appeal for anyone with information to come forwards to us.
“There were a large number of people present when this happened and I urge those people to come forward. You may be able to help us significantly in our investigation.”
