Flowers and handwritten notes have been left outside the house where a schoolgirl was murdered, describing her as "heaven's angel".
The 15-year-old, named locally as Megan-Leigh Peat, was killed at an address in Ampthill, Bedfordshire, early on Saturday morning.
Officers attended the property after receiving a report a girl had been fatally injured.
Local reports claimed the teenager was stabbed to death at a house party, but officers have refused to comment on this.
Bedfordshire Police only said a 19-year-old man had been arrested in connection with the incident.
Tributes to Megan-Leigh have been left outside the semi-detached home, which has been cordoned off by police.
One friend wrote on a card left at the scene: "The emptiness and hurt you have left so many of us with is unimaginable.
"A beautiful girl on the inside and out, whose life was just beginning... Such a tragedy, so surreal right now.
"Heaven's angel. Rest forever peacefully."
Another note read: "Beautiful Megan, I remember the day you were born, the joy you brought your mum and dad to have a daughter and to give your two brothers a little sister.
"Then you grew into a happy smiley teenager. Heaven has gained an angel."
Other school friends who laid flowers and a photograph at the cordon described
the teenager as a "party girl" and "the hero of the school".
Chelsie McAneny, 16, said she shared lessons with Megan-Leigh at Harlington Upper School in Dunstable.
She said: "Everyone loved her, she was bubbly and popular and she stuck up for everyone, even when she was down.
"She was a party girl, she loved it. You could hear her a mile away. Everyone would say she was a good friend."
Another friend added: "Megan was the hero of the school, she was beautiful and she was always so supportive. The teachers loved her."
Neighbours said the community in the small town had been shocked by the incident, with one describing the scene as "like a movie set".
The man, who asked not to be named, said he returned to his home near the murder scene at around 2.30am on Saturday.
He said: "When I left it was all quiet but by the time I got back there were police vans and cars and paramedics outside the house.
"There must have been six police cars. I woke my girlfriend to show her and she was in shock. It was like a movie set.
"One of the neighbours came over to fill me in on what had happened. It's shocking because nothing ever happens in Ampthill, it's the sort of place where you don't even get a dirty look in the pub."
The resident said he had heard loud music coming from the house on a number of occasions but had not noticed anything at the property on Friday evening.
Another neighbour, who also asked not to be identified, said a woman in her 40s and her teenage son moved into the rented house around 12 weeks ago.
She said the boy celebrated his 18th birthday about a month ago.
