Detectives investigating claims of historical child sex grooming have arrested 44 people.
Four women complained of being abused between 1995 and 2005 when they were aged between 12 and 16.
During the course of an investigation police said they had arrested dozens of people across Bradford, Leeds, Kirklees and other areas of the country.
Those arrested within the past two weeks include 36 men and three women. Five other men were arrested earlier.
