Police have arrested a 35-year-old man in connection with the murder of teenage model Sally Anne Bowman.
Sally Anne Bowman had only just turned 18
The 18-year-old was bitten, sexually assaulted and stabbed to death yards from her home in South Croydon, south London, last September.
The suspect was arrested in Surrey on Tuesday night and is being questioned at a south London police station.
Ms Bowman, who also worked as a hairdresser, had dreamed of being on the cover of Vogue magazine.
The attack took place after the model had been on a night out in Croydon before going to a friend's address and heading home.
Neighbours heard the teenager, who turned 18 just a week before her death, screaming in the early hours and her body was later found on the pavement next to a skip.
Detectives made a fresh appeal on the BBC's Crimewatch programme in April, based around a new e-fit of a suspect who has been linked by DNA to an indecent assault in July 2001.
It was created with the help of the victim of that attack and released for the first time last month, six months on from Ms Bowman's death.
And in March, detectives set up a DNA screening centre in South Croydon, asking local men to provide their DNA voluntarily.
Detectives had expressed a wish to screen 4,000 local men matching the general description of the suspect.
Hundreds came forward but thousands more still remain to be screened.
