BEIJING, Sept. 29 -- British teenage model Sally Anne Bowman was murdered after her killer had tried to rape her, police said.

    Detectives investigating the stabbing of the 18-year-old model have released two men without charge.

    Police said on Wednesday that Sally Anne was partially clothed when her body was found by a neighbour at 6.30am on Sunday.

    Detectives are hoping her stolen white leather Prada handbag and black Samsung D500 mobile phone may provide vital clues. Her passport is also missing.

    On the night she died, Sally Anne was out with friends in Croydon town centre. She got a taxi to Katherine Street close to her home at about 2 a.m.
