A woman taking her dog for an early morning walk has been subjected to a terrifying sex attack.

The 50-year-old was walking the dog in Wibsey Park, Wibsey, Bradford, at 6.25am on Tuesday when she was attacked from behind and forced into some bushes.

Detectives said she was then subjected to a serious sexual assault during which she suffered a number of injuries.

The terrified woman ran to a friend's house where they raised the alarm.

The victim, believed to live locally, was taken to Bradford Royal Infirmary and released after treatment to her injuries.

So far she has been unable to give an accurate description of her attacker but specially-trained officers were continuing to speak with her today.

Detective Inspector Rob Sumner, who is leading the investigation, said he wanted to hear from anyone who was around the park at the time.

Officers are also seeking information about an old, dark coloured, Sierra-type car seen parked in the entrance to the park.

Det Insp Sumner said this may or may not be linked to the attack and urged its owner to come forward.

"For a woman to be attacked in a park like this is absolutely horrific.

"She has been put through a terrible ordeal and is obviously very traumatised by it."
