Police investigating the deadly stabbing of a teenage boy in Bath have urged people not to share footage of the attack on social media.
Mikey Roynon, 16, from Kingswood in Bristol, died after being attacked at a house party in Eastfield Avenue in the Weston area of the city at about 11pm on Saturday.
Fourteen teenagers have been arrested so far.
All have been released except a 16-year-old from Wiltshire and 15-year-old from Dorset, who remained in custody and were still being questioned by detectives on Tuesday.
It can be an offence to identify anyone who witnessed all or part of the incident as well as those who have been arrested— Detective Inspector Mark Newbury
Specialist officers searching the scene and surrounding area on Monday found a knife, though Avon and Somerset Police have not said whether it is believed to be the murder weapon.
In a statement on Tuesday, Detective Inspector Mark Newbury, senior investigating officer, said sharing videos of the stabbing could be illegal and prejudice a future court case.
He said: “Our investigation is progressing and we have already build up a fairly good picture of what took place.
“Around 50 to 60 people, the majority of which were children, were inside the property at the time and sadly witnessed things no one would want them to see.
“As a result, we are working closely with our partners to ensure they have access to support, including specialist counselling.”
He added: “I’d like to remind people this is a live investigation and it is extremely important there should be no commentary or sharing of information or images online which could in any way prejudice any future proceedings.
“It can be an offence to identify anyone who witnessed all or part of the incident as well as those who have been arrested.
“I’d also like to remind people of the impact the sharing of images, footage or even discussing the incident online may have on Mikey’s family.
“They are already going through the most difficult of times and you may cause them further upset.”
