Jermaine tried to run from the attackers but was stabbed 20 yards from the shop. 

A post-mortem examination has given the cause of death as a single stab wound to Jermaine's leg.

Detective Chief Inspector Tony Lynes, leading the investigation from the homicide and major crime command, said: "I'm really keen to hear from anyone who was out with Jermaine that night.

"I can understand that you may be worried about coming forward, but I would like to reassure you that experienced detectives will deal with you sensitively. We will help you through the process of talking to us, as it is vital we get information to help us catch the men responsible.

"Also, if anyone saw the attack on Jermaine please get in contact with us and tell us what you saw."

The investigation into Jermaine's murder was launched after police were called to Georgia Road, near the junction with Green Lane in Thornton Heath last Tuesday.

Members of the public rushed to help Jermaine after he was injured, before police officers and the London Ambulance Service arrived.

Jermaine was pronounced dead at the scene shortly before midnight.

DCI Lynes said: "Our investigation has also established that there was an incident in the same area as Jermaine was attacked at around 3pm to 4pm on that Tuesday afternoon.

"This was an altercation involving a number of teenagers armed with sticks, and some on mopeds, wearing balaclavas."

Police are investigating the idea that the two incidents are linked,

DCI Lynes said: "Jermaine's family are devastated by his loss, my thoughts are with them at this difficult time. Please help us find the people responsible for taking their son from them."

Anyone with information that may assist the investigation should call the homicide and major crime command incident room on 020 8721 4868 on via 101.
