A major inquiry is under way after an alleged sex attack on a teenage girl.

Detectives are investigating reports that the 15-year-old girl was attacked in Dewsbury’s popular Crow Nest Park at the weekend.

And although few details have been released, it is believed police are looking at links with a number of previous sex offences in the area.

They are examining reports of a man exposing himself several times in recent weeks.

The victim of the weekend attack is now being interviewed by specially-trained detectives to try to piece together exactly what happened.

Police say the incident is said to have taken place some time between 10pm and midnight on Friday.

Over the weekend a blue and white tent was erected at the scene as police officers and forensic experts sealed off the area.

There was initial mistaken speculation that a body had been found. But West Yorkshire Police later confirmed they were investigating a sexual assault.

Officers remained at the scene for much of the weekend and were also prominent at a narrow lane in Carr Lane, Dewsbury Moor, less than a mile away.

The lane was sealed off with blue and white police tape.

The investigation is being led by Detective Chief Inspector Simon Atkinson, from West Yorkshire Police’s Homicide and Major Enquiry Team.

A West Yorkshire Police spokesman said: “Inquiries are ongoing.”

Reports of this latest sex attack come shortly after detectives revealed details of a sex pest who had exposed himself FIVE times in the Kirklees area over the last few months.

In the first two offences the victims were teenage girls aged 15 and 13.

The first incident was in Cawley Park Lane, Heckmondwike, as a girl was walking to school.

She saw a man hiding in bushes, exposing himself.

Three more incidents happened on the Spen Valley Greenway, which runs from Cleckheaton through Liversedge and Ravensthorpe.

Kirklees councillor for Cleckheaton Kath Pinnock, the Lib Dem party leader, said: “These incidents are very disturbing and it must be horrifying to be on the receiving end of them.

“It’s very worrying for parents and young people.”

Crow Nest Park is a popular recreation area and was opened to the public in 1893, founded upon the landscaped gardens of a country house estate.
