A SEX attack victim has spoken of the moment when she heard a pervert walking up behind her, preparing to pounce.

The Darwen woman -- whose identity must be protected -- said the man approached her in the multi-storey car park, in Blackburn town centre.

The attack, at 9.25am on Sunday, occurred in the same weekend two women were raped in unconnected incidents in East Lancashire.

The 22-year-old office worker said the man grabbed hold of her and asked her for sex, although she managed to escape and ran straight to the police station.

Police today said they were not linking the incident with either of the two rapes which occurred at the weekend.

Shortly after 9pm on Friday a 32-year-old woman was attacked on waste ground in Sandringham Road, Darwen. And on Saturday -- again at 9pm -- an 18-year-old woman was attacked in her own home, on Blackburn Road, Great Harwood.

Inquiries into both incidents are ongoing.

The woman involved in the attack on Sunday described her ordeal as 'terrifying.'

She said: "I saw him in the car park when I was parking up, and I noticed he had no coat on, which I thought was strange.

"I could hear him walking after me as I was heading to the stairs but I just ignored him. He grabbed me and turned me round and said 'I want sex with you.'

"I managed to shrug him off and ran down the stairs and straight to the police station. It was so frightening, I still feel very scared now.

"I have been very lucky, but the implications were awful."

Detective Inspector Jim Elston confirmed the incident was being investigating, but said police were not connecting all three incidents.

He said: "Clearly this is an extremely upsetting incident.

"At this stage, we are not linking it with the assault in Darwen or Great Harwood, but we would urge women, particularly now that dark nights are drawing in much earlier, to exercise common sense.

"Where possible, they should consider making any journey in an illuminated street and try to avoid walking alone and in the dark."

The description given to police was of an Asian man, 5ft 7ins tall with long hair.

He was wearing a dark jumper, jeans and trainers.
