West Yorkshire police arrested 55 men for child abuse between 2002 and 2009.
The men have been arrested in recent months at addresses in Dewsbury, Batley and Bradford.
All were subsequently released under investigation.
The investigation came after seven women reported being sexually abused as children.
They said that this happened mainly in Dewsbury and Batley between 2002 and 2009.
Detective Inspector Ian Thornes said, "This survey shows the troop's continuing commitment to investigating both current and non-current 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."
The officers requested that all other persons who were recently abused or not should be reported to the police.
