Two people have been arrested in connection to the murder of Croydon teenager Jermaine Goupall.

A 16-year-old boy and an 18-year-old woman were arrested in the Thornton Heath area this morning (August 11) on suspicion of murder.

They have been taken to a south London police station where they remain in custody.

Police were called at around 11pm on Tuesday, August 8, to a teenager stabbed in Georgia Road near the junction with Green Lane, Thornton Heath.

Officers and the London Ambulance Service attended and found the victim suffering from stab injuries.

He was pronounced dead at the scene shortly before midnight

Detective Chief Inspector Tony Lynes, leading the investigation from the Homicide and Major Crime Command, said: "Jermaine was out with his friends when they were confronted by a group of armed men who had made attempts to hide their identities by wearing balaclavas. Jermaine tried to run away from the men, but sadly was attacked about 20 yards from the shop suffering a number of stab injuries.

"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."

An eyewitness has told of the moment he rushed over to help the schoolboy who had been stabbed multiple times with a "samurai sword".

A post-mortem examination was carried out on Wednesday, 9 August and gave cause of death as a single stab wound to Jermaine's leg.

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.

"One line of enquiry we are exploring is if there is a link between this incident that afternoon and the later altercation that led to Jermaine's death.

"If you were in the area around that time and saw anything, or know who was involved in this fight please call our incident room.

"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."
