Police are appealing for witnesses after a teenage girl was sexually assaulted at night in a Dewsbury park.

The attack in Crow Nest Park happened as the 19-year-old was sat with her friend on a bench near to the museum.

Two males walked up to her and tried to speak to her, but she told them to go away and made her way to leave.

As she did so, she was indecently touched by one of the men who then cycled away.

The first man was described as tanned, aged around 16, 5ft 1in tall, of a slim build and with short dark brown hair.

He was wearing a blue and white top and jogging bottoms and was riding a BMX style bicycle.

The second suspect had paler skin and was 5ft tall, with ginger hair and a stockier build.

He was also wearing a white and blue top and riding a BMX style bike.

Neither of the men spoke English.

Now police would like to speak to anyone who has information about the attack, which happened between 7.20pm and 7.50pm on May 20.
