660 suspected paedophiles have been arrested as part of a six-month operation targeting people accessing child abuse images online. The National Crime Agency (NCA) said the 660 included doctors, teachers, scout leaders, care workers and former police officers. More than 400 children have been protected as a result, the agency said. Arrests were made across the UK and the majority of those held had no previous contact with police. The NCA said 39 of those arrested are registered sex offenders. Charges already brought range from possessing indecent images of children to serious sexual assault. The NCA stressed that none of those arrested is a serving or former MP or member of the Government.
