Two boys and a 46-year-old woman have been arrested over the murders of two teenage boys in Bristol on Saturday.
The male suspects, aged 15 and 16, have been arrested on suspicion of murder, while the woman was detained on suspicion of conspiracy to murder.
All three are currently in police custody.
Detectives investigating the deaths of Mason Rist, 15, and Max Dixon, 16, have so far arrested eight people.
The two boys died after being stabbed in Ilminster Avenue at around 11.20pm.
Avon and Somerset Police previously said a group of people fled the scene in a car shortly after the teenagers were attacked.
Detectives are yet to establish if the suspects and victims knew each other, or whether the boys died in a case of possible mistaken identity.
Others arrested in connection to the incident include:
• A 15-year-old boy arrested on suspicion of murder, who has since been bailed
• A 22-year-old man arrested on suspicion of murder, who remains in custody
• A 44-year-old man arrested on suspicion of murder, who remains in custody
• A 26-year-old man arrested on suspicion of assisting an offender, who remains in custody
A 20-year-old man was also arrested on suspicion of murder and possession of an offensive weapon in a private place. He has been bailed but no further action will be taken related to the murder offence, police said.
Superintendent Mark Runacres, Bristol's policing commander, said the force had been making "significant progress" with its inquiry and said relatives of the victims had been updated.
