Eight teenagers have been arrested on suspicion of murder following the fatal stabbing of a 16-year-old boy at a party in Somerset.
Emergency services were called to an address on Eastfield Avenue, in Bath, just after 23:00 BST on Saturday.
Six boys and two girls are being held between the ages of 15 and 17.
Avon and Somerset Police said eight teenagers were arrested on a bus traveling on Lansdown Lane at 23:30 and remain in police custody.
The force added that a 35-year-old woman was also stabbed but was released from the hospital.
Residents gave the boy first aid before paramedics arrived, but the boy died at the scene.
Inspector Ronald Lungu, of Bath Neighborhood Team, said: “This is a tragic incident and this morning we offer our condolences to the family of the dead boy.
“Police arrived on the scene within minutes of receiving the first call and a homicide investigation is underway.”
He added the boy’s family had been notified and was “understandably devastated”.
Police said an autopsy to determine the boy’s cause of death would take place in due course.
There is a large fence at Eastfield Avenue while police investigate.
“We have identified a number of witnesses and we will take official statements from them in the near future,” Ch Insp Lungu added.
“The community can expect to see a significant police presence in the area over the next few days, while officers and police officers take a number of actions including forensic examination, review of the CCTV footage and door-to-door investigations.”
Anyone with information is asked to contact the force.
