In 2016, police discovered a child sex abuse network run from Berkhamsted in Hertfordshire, England. Eight of the men were convicted and some received significant prison sentences.
The discovery resulted in a police investigation in 2017 which helped to uncover many other child abusers worldwide.
Operation Pendent was a child sex abuse investigation in 2017 into the Berkhamsted network; it was led by Hertfordshire Constabulary, and helped to uncover many other child abusers worldwide. One suspect in the United States was arrested within 48 hours of information being passed to Homeland Security.
For much of 2017, media reporting on the criminal proceedings members of the network was under reporting restrictions. Restrictions were lifted on 20 December 2017, when six offenders were sentenced. A seventh was jailed in February 2018.
