The dismembered body of a missing teenager has been found dumped near a stairwell on a housing estate.
Forensic experts have left the flats with evidence bags
Officers found the body of Rochelle Holness, 15, at Milford Towers, Catford, south London, on Wednesday. It is thought she had been abducted.
Police were alerted by ambulance crews who had been called to reports a man had injured himself. Police found body parts in bin bags outside the flats.
A man and woman, both aged 47, are being questioned by police.
Distraught family and friends have taken flowers to the scene, which is behind a police cordon, and forensic experts have been seen leaving with evidence bags.
Officers have also been carrying out door-to-door inquiries.
Rochelle, from Lewisham, south London, was last seen at about 1900 BST on Sunday after saying she was going to call her boyfriend from a phone box on the Milford Towers estate.
When she failed to return home that night her parents assumed she was staying with friends.
It was only when her boyfriend called on Monday, to say he had not heard from her, that they became concerned.
She was reported missing on Tuesday and her body found the next day.
A post-mortem examination was carried out on Thursday.
Det Supt Paul McAleenan said: "At this early stage, it is not clear when Rochelle was killed.
"I want to hear from anyone who was in the area at any time from Sunday evening to the early hours of Wednesday."
Residents on the estate said there is regular trouble in the area.
Christine Stewart, 40, has lived there for ten years, but plans to leave as soon as her son goes to secondary school.
"It is not a nice area," she said. "There is lots of petty theft and my neighbour next door was burgled.
"She found somebody in her house and the woman the other end was burgled at the same time.
"It is a pretty nasty area - you just lock your doors and windows and hope no one bothers you."
