Police are appealing for information one week on from the murder of 14-year-old Jermaine Cools in Croydon.
Police were called to a fight on London Road, near West Croydon Station at around 6:30pm on Thursday, November 18.
A boy with stab wounds went to a South London hospital at around 7pm and died a short time later.
He was formally identified as 14-year-old Jermaine Cools.
Detective Chief Inspector Richard Vandenbergh, of the Met’s Specialist Crime Command is asking anyone from the public who has information to get in touch.
He said: “We know that this was a murder which happened in a public place in the middle of a busy, commuter time and people will have witnessed Jermaine being attacked.
“I am asking for anyone who was in the area to cast their minds back to last Thursday.
“Were you at or travelling past the station at around 6.40pm? Did you see anything that might help police find the people responsible for Jermaine’s murder?
“Jermaine was a central member of his family, and his parents have been left devastated and without a son.
“At the very least, they are owed an explanation for why their son was killed, and police will continue to work relentlessly to ensure the people responsible are held to account.
“If you can help, please get in touch with my team or leave information completely anonymously with Crimestoppers.”
A murder investigation was launched on Thursday, November 18 after police were called to reports of the fight, involving a number of people.
Officers attended but no suspects or victims were found.
Shortly after 7pm, police attended a south London hospital after a 14-year-old boy self-presented with stab wounds.
A post-mortem examination gave Jermaine’s cause of death as multiple stab wounds.
There have been no arrests and enquiries continue.
