A detective has criticised the glamorisation of knife crime as police released the name of a 16-year-old boy who was stabbed to death in Liverpool.
Daniel Gee-Jamieson was found by officers on Belle Vale Road in Gateacre at about 9pm on Tuesday and later pronounced dead in hospital.
A 17-year-old boy has been arrested on suspicion of his murder.
Detective Chief Superintendent Chris Green, from Merseyside Police, said the message that carrying a knife was illegal and dangerous was not getting through to all young people.
He said: "We can all look across social media and see some people will glamorise knives, through music or through pictures and images, but I want to cut that short. It is absolutely not glamorous.
"It is not glamorous for this young 16-year-old. It's abhorrent.
"There is nothing glamorous about it whatsoever and that's the message that we have to be really strong about. It's quite the opposite.
"The person responsible, or people responsible, for this will spend a long time behind bars and that is not glamorous.
"The family of this young victim will live with this forever and that is not glamorous."
He said the force would continue to work "relentlessly" with partners in schools and other organisations to get the message across to young people.
Mr Green said officers believed Daniel had been stabbed following an altercation within a group of teenagers on a park off Belle Vale Road.
He appealed for witnesses who may have seen a group of 10-15 teenagers, believed to have fled along a disused railway line known as the Loop Line, following the incident.
He said: "We are appealing for any individual who was there and saw what happened to come forward.
"We are appealing to parents of those young people who were in that park - if you know your son or daughter was in that area, please come forward.
"We will trace everyone who was on that park."
On Wednesday forensic officers were carrying out examinations on Belle Vale Road.
Police were also searching a house linked to the arrested teenager and inquiries were made at nearby schools.
Residents said the incident happened as England prepared to take penalties in their World Cup match against Colombia.
Darcy Hartley, 74, said she heard raised voices outside at about 9pm.
"I was just watching the game and I heard the noise," she said. "It sounded like a large group of boys. Then a lot of police turned up.
"I walk my dog every day and I usually see boys smoking in the path which leads to the park.
"Sometimes they fight amongst each other."
Another neighbour, who did not want to be named, said: "I only realised something was happening when I saw police and paramedics.
"It was just near the end of the match, before the penalties.
"I went out and had a look and could see the lad being treated by paramedics just over the road.
"It's terrible, it seems to be getting worse. Life is cheap these days, with people carrying knives around."
