Wiltshire Police have made four arrests in connection with the national crackdown on internet child pornography.

No details have been released about the professions of those arrested in the county.

Hundreds of child welfare professionals, including police officers, care workers and teachers, have been arrested in the UK as part of the inquiry.

Police have been running Operation Ore into alleged UK users of a US child pornography website.

Last week Northamptonshire Police arrested and bailed five men on suspicion of making indecent photographs.

Three more men were arrested by the force on Wednesday.
