A 16-year-old boy killed on the streets of Coventry was the stabbed to death because of his postcode, his sister said.
West Midlands Police said Jaydon Washington James and his friends were attacked in Deedmore Road, Wood End, just before midnight on Saturday.
The teenagers were taken to hospital, where Jaydon died, police said.
Paying tribute to her brother, Jayda James said in a Facebook post that Jaydon died simply because of the neighbourhood he lived in.
She wrote: Jaydon was the sweetest, funniest, most kind-hearted boy. He didnt fight, he wasnt part of a gang, he was friends with everyone and tried to keep the peace whenever he could.
Jaydon was stabbed to death because of his postcode, because he was a Wood End boy. I cant believe someone took my brothers life simply because of the neighbourhood he lived in.
Jayda added: All we want to do now is find out who took Jaydons life, so we can seek justice.
If you have any idea who any of the GROWN MEN were that were involved in the incident that took place in Wood End last night please message me or call 101 and you can report it anonymously. These men are murderers. Please help us get #Justice4Jaydon.
Detective Chief Inspector Edward Foster of West Midlands Police said: We have officers working around the clock to find those responsible for this horrific and deeply tragic attack.
Jaydon had only just turned 16 with his whole life ahead of him.
Words cannot describe the anguish that his family are going through, and we will leave no stone unturned in the hunt for his killer.
We have several lines of enquiry, but I would still urge anyone with information to contact us as soon as possible.
