Two men arrested in connection with the murder of rapper Carl Beatson Asiedu have been bailed by police.
The body of the 19-year-old from Norbury was found in a car which had been pulled over by police for jumping a red light on Saturday morning.
Three cars had been pulled over by police for jumping a red light in Baylis Road, Waterloo, and the dead teenager was discovered in one of the vehicles.
A post mortem revealed the teenager had been stabbed to death. According to friends the popular teenager, also known as Charmz, was about to release a single.
He was a student and just finished his first year at De Montfort University in Leicester.
In his spare time he toured other universities as a rapper with friend DJ Sayps as half of the music duo Kid n Play.
Police believe he had been stabbed earlier outside a Kennington nightclub where he had earlier performed.
A police spokesman said: "At this early stage it is believed the incident took place outside the Club Life nightclub in Goding Street, SE11, approximately one mile from where the cars were stopped.
"At around the same time as the first victim was discovered, a second man - also believed aged 19 years - was discovered in Goding Street."
Detectives are appealing for anyone who was in the Goding Street area at about 5am and may have witnessed the incident to come forward.
At present anyone with information is urged to call Crimestoppers on 0800 555 111.
