Simon Chilton was convicted last week of a string of sexual offences against two children who he abused between 2013 and 2018.
The 36 year-old, formerly of Glover Close, Clacton, was arrested after the offences came to light in November 2018.
Specialist detectives from Essex Police’s child abuse investigation team carried out a thorough investigation and supported the victims, including utilising new measures which meant they did not have to give evidence at his trial.
Following a trial at Chelmsford Crown Court, Chilton was found guilty of seven counts of rape, six counts of sexual assault, four counts of sexual assault by penetration, and one count of assault by beating.
At the same court today (14 May) he was jailed for 21 years with an additional year on licence.
