West Yorkshire detectives have arrested 55 men as part of an investigation into historical allegations of child abuse.

The police said the men were arrested after seven women claimed to have been sexually abused between 2002 and 2009 as children in the Dewsbury and Batley areas.

The men were arrested, interviewed and released in Dewsbury, Bradford and Batley in recent months, and released for further investigation.

DI Ian Thornes, who led the investigation, described the sexual abuse and exploitation of children as a "heinous and heinous crime" and called on anyone who was a victim to report it to the police.

He said, "Please be assured that you will be heard by professionals experienced in dealing with this type of crime."

He said children's protection and safety remain the "top priority" for West Yorkshire police. The force is working with local authorities, other organizations and charities to help the victims and bring the perpetrators to justice.

He said, "This investigation shows the troop's continuing commitment to investigating both current and recent sexual offenses against children.

"Sexual abuse and exploitation of children is a heinous and heinous crime that affects some of the most vulnerable people in our society.

"We have specialized protection teams in each district in West Yorkshire, including police officers who deal with both current and recent child abuse and the sexual exploitation of children."
