DETECTIVES hunting an attacker who snatched a schoolgirl have arrested a man.

The 57-year-old Calderdale man has been released on police bail pending further inquiries.

Police have stressed that the investigation remains ongoing and have urged anyone who recognises the e-fit image they have released to contact them.

The attacker has been dubbed ‘pigman’ because of his distinctive facial features.

The 14-year-old victim was abducted as she walked along Crossley Lane in Mirfield a week last Sunday.

She was driven to a dark field at Hartshead before her abductor dragged her from the car on Hartshead Lane..

But two people were in the field and when the man realised he was in danger of being rumbled, he escaped.

Police are again appealing for the two people in the field to contact them as they believe they may hold vital clues.

A West Yorkshire Police spokesman said: “We still need these two people to contact us as they may be able to assist our inquiries.

“They have failed to respond so far to our pleas for them to come forward and we would urge them to do so now.

“There has been a good response since we published the e-fit image and we would urge people to look at this man’s face again and come forward with possible names.’’

The attacker, whose motives are thought to be sexual, had a distinctive pig-shaped nose and big lips. He may walk with a limp or in a peculiar way, and spoke with a local accent.

He drove a blue people carrier and is white, aged between 40 and 50, and slim with grey/blond short hair.

He is thought to have been wearing an Adidas cap, a jacket, and either blue or black tracksuit bottoms.

He also wore a balaclava-type face-covering when the attack took place and was seen to drive the vehicle wearing the mask.

Anyone who can put a name to the face and description, or has any other information, should contact Det Sgt Simon Leek or Det Insp Paul Harrison on 0845 6060606 or the incident room on 01274 373642.
