Detectives investigating the murder of a teenage girl continue to question a 19-year-old man.
The 15-year-old, named locally as Megan-Leigh Peat, was killed at a house in Bedfordshire in the early hours of Saturday.
Police said officers attended the property after receiving a report that she had been fatally injured, but would not comment on neighbours' claims that she was stabbed to death at a house party.
A Bedfordshire Police spokesman said a post-mortem examination will take place.
Police said a murder investigation was launched after a woman died from "serious injuries" on Saturday.
Officers found the body at a property in Ailesbury Road, Ampthill, at around 1.30am after receiving a report that a woman had been fatally injured.
Scenes of crime officers started a full forensic examination of the semi-detached house and the surrounding area which was expected to continue today.
Megan-Leigh's friends paid tribute to her on social networking sites Facebook and Twitter.
A Twitter user named Mrs Simmons wrote: "Horrible waste of a beautiful life, may justice be served whoever caused this. RIP."
Annie Austin tweeted: "You were taken from us far too young ... always in my heart beautiful." Other friends described the teenager as a lovely girl who would "never be forgotten".
One friend posted pictures of the teenager with the caption: "my beautiful bestfriend, who was murdered last night. r.i.p beautiful. i love you so much."
Another said: "Still can't believe this has happened, going to miss seeing you up to mischief at school."
