A 15-year-old boy who was stabbed to death was murdered in an "awful premeditated attack", police have said.

Jay Hughes was knifed in Bellingham on Thursday at around 5.20pm and died several hours later in hospital.

Childhood friend Tayla Ann Warwick, 19, said he was a "loving and thoughtful" boy who had loved roller skating and riding his bike.

The 19-year-old said: "It's so shocking, I spoke to him the other day.

"He was the kindest person, he was so loving and thoughtful, he was well known with everyone."

Less than 24 hours later, a 17-year-old boy was fatally stabbed outside Clapham South Tube Station.

The second killing marked the 115th homicide in the capital so far this year, of which 19 victims have been teenagers.

Murder detectives have appealed for information and witnesses to what they say was a planned attack on Jay.

Detective Chief Inspector Chris Soole said: "We know that this was an awful premeditated attack on a young boy who sadly lost his life as a result.

"I would appeal to anyone with information to get in touch with us.

"Those responsible must be caught and brought to justice. Any information passed to police will be treated with the strictest confidence."

Medical staff worked to keep Jay alive following the attack on Randlesdown Road in Bellingham but could not save him.

A cordon was placed around Morley's chicken shop and other businesses on the road.

Five children in school uniforms placed flowers and cards on railings at the scene on Friday.

Deanne Wright lives in the area and said she used to see Jay on the bus every day.

The 36-year-old went to Morley's on Randlesdown Road after a friend told her about the incident, saying: "I saw him, he was on the floor, I saw him lying there.

"I just know he was a sweet little boy."

A woman who asked not to be named said: "I don't know if he was involved in a gang but I live here and I never thought Bellingham was coming to this.

"I'm just upset because the first thing I thought was that it was my son. I was on my way to Morley's to get food for my kids, I thought it was my son but it wasn't."

A Section 60 order - which allows police officers in the area to stop and search a person with suspicion - has been authorised in the wake of his death.

A post-mortem examination is scheduled to take place at Greenwich mortuary on Sunday.
