A 16-year-old boy has been found stabbed to death in Blackpool.
Sam Brown died at the scene on Cockerham Walk
Sam Brown was found by police on Cockerham Walk in Grange Park in the early hours. He was with a 28-year-old man who had also been stabbed.
The teenager died at the scene. The other victim was taken to the Blackpool Victoria Hospital. His injuries are not life-threatening.
Officers say they are looking for a third man over the attack. They will question the injured man later.
Det Ch Insp Neil Esseen, leading the investigation, said: "We've launched a murder investigation and are appealing for any witnesses who may have seen anything to come forward.
"We realise an incident took place in the early hours of this morning, but we believe someone may have seen something.
"The 16-year-old received a single stab wound and was dead at the scene.
"A 28-year-old man has been taken to the Vic suffering from stab wounds, but his injuries are not serious."
Much of Cockerham Walk has been cordoned off while a forensic team examines the scene for evidence.
Local resident James Cairns said: "The forensic people have been up and down the street looking on our front paths - it's all very busy."
Mr Cairns said Sam lived with his parents and brother near the scene of the stabbing.
He added: "You read about this sort of thing in the papers but you never expect it on your doorstep.
"It's a big shock. Grange Park has got a bit of a dodgy reputation for violence but in the years we've been here we've never been burgled.
"It's as good as anywhere in Blackpool nowadays."
