A 17-year-old girl killed in the Wiltshire town of Calne has been named as Ellie Gould.
The teenager was pronounced dead after emergency services were called to a house in Springfield Drive at 3.15pm on Friday.
Wiltshire Police detained a 17-year-old boy, who was known to Ellie, in the nearby town of Chippenham later that afternoon.
He was arrested on suspicion of murdering Ellie, a Year 12 pupil at Hardenhuish School, and remains in custody.
A force spokesman said inquiries continue to ascertain the circumstances surrounding Ellie's death.
Superintendent Conway Duncan said: "Our thoughts remain with Ellie's family, her friends and schoolmates.
"Ellie's family will continue to receive support from specially trained officers and we are aware that her fellow pupils are being encouraged to seek support being organised by Hardenhuish School.
"We fully appreciate the level of shock, anxiety and upset in and around Calne and Chippenham and our officers are continuing to progress their inquiries as swiftly and diligently as possible.
"I would like to take this opportunity to thank our communities in Calne for the support and patience they have shown our officers as they undertake their inquiries."
The force released a picture of Ellie, chosen by her family, who have asked for privacy.
In a statement, Hardenhuish School said: "The Hardenhuish community is shocked and saddened by the tragic death of Ellie Gould.
