Avon and Somerset Police are appealing to people in Bristol who know a man who wears Paco Rabanne 1 Million after a woman identified her sex attacker's aftershave.

Detectives believe the distinctive smell of the French aftershave – described by the manufacturer as "seductive, elegant and charming" – could be an important clue in their hunt for a sex attacker in Bradley Stoke.

A 22-year-old woman was assaulted on Saturday 6 June, and believes she remembers the smell of the man who attacked her.

Detective Inspector Dom Graham, leading the investigation, said: "This was a particularly nasty and unprovoked stranger assault. I want the public's help with any aspect of this enquiry, and my appeal today is – if you know anyone who wears this aftershave, call us."

The attacker is described as white, possibly in his mid-thirties, about 6ft 1ins tall and is well-built with broad shoulders.

He was wearing a grey hooded top with a central zip and the hood had white strings that were frayed at the ends.

His shoes were dark, with laces and high-cut up to the ankles, with thick soles of a different shade.

Police have been carrying out extra patrols in the area and along a path called Concorde Way that runs beneath Bradley Stoke Way.

Signs appealing for information have been put on fences and lamp posts, and officers have carried out house-to-house calls and spoken to people who use the route.
