New Online Portal For Submitting Information 

It is now easier for members of the public to provide information directly to the team investigating child sexual abuse in Rotherham between 1997-2013. A portal accessible at means information can be provided by members of the public without them needing to pick up the phone or go into a police station - something that we hope will encourage people to come forward.

The portal is hosted on the Home Office Large Major Enquiry System (HOLMES) – it’s a national IT system used by UK law enforcement for the investigation of complex major incidents and serious crimes such as murder, serial offences, high value and cross-border crime and allows officers to manage huge amounts of information and intelligence.
