25 men, mostly from West Yorkshire, have today been charged with allegedly committing sexual abuse against a single child who was aged under 16.
The men - aged between 23 and 42 and almost all from West Yorkshire - are charged with a number of offences including rape, trafficking, voyeurism, grooming and supply of a Class B drug to the child, who cannot be named for legal reasons.
One charge relates to another child who was allegedly under 16 at the time, who also cannot be named. The alleged offences took place between 2006 and 2011 in Calderdale.
A West Yorkshire police statement said: "They relate to, in the main, one female victim who was aged under 16 at the time. One of the allegations also relates to a second victim, which occurred during the same time period."
