A NURSE was pushed to the floor and sexually assaulted by a man who pounced on her as she walked to work.

The terrified 21-year-old was attacked in Shadsworth Road, Blackburn, close to the junction with Haslingden Road, as she made her way to the maternity unit at Queen's Park Hospital.

She fought back as the attacker tried to snatch her handbag but he then turned on her, pushed her to the ground and knelt on her before committing a serious sexual assault.

The victim managed to break free and ran to a nearby Miller Homes building site where workmen comforted her and raised the alarm.

Police today urged the public to help catch the attacker.

They were due to ask hospital bosses to warn other nursing staff about the dangers of walking alone.

Detective Sergeant Paul Murphy, from Blackburn CID, said: "The victim was simply walking to work at 12.45pm yesterday when she was attacked by this man, who walked up behind her.

"She managed to hold on to her handbag when he tried to snatch that, but was then subjected to a very serious sexual assault."

Mr Murphy added: "We would appeal for any witnesses to come forward or if anyone recognises the description to contact us immediateley."

The woman was today described as being 'badly shaken' although she did not suffer any serious injuries.

The attacker is described as being white, around 20-25 years old, of medium build with short hair.

He was wearing a blue, three-quarter length jacket and denim jeans.

He was also described as having blond stubble.
