Liam Clarke (35), appeared before Exeter Crown Court for sentencing after being found guilty of 16 offences including rape of a child, sexual assault and inciting a child to engage in sexual activity.
The charges relate to three victims, with offences being committed in Hampshire and Devon dating from 1997 to 2016.
Clarke, of Joseph Locke Way in Crediton, was remanded in custody after his arrest in July 2017 and remained on remand until the trial began on March 26, 2018.
DC Katy King, of the Devon and Cornwall Police Public Protection Unit in Exeter, said: “This has been a long and complex investigation involving historical sexual abuse over a number of years by Clarke.
“It has been an extremely traumatic and emotional time for all three victims. He has been on remand since July 2017 and this result finally provides these vulnerable victims with some closure.
“They have shown resilience and patience throughout the investigation. It is hoped that they can draw strength from the verdict and can live knowing that they have done everything they can to help protect others.
“We wish to thank everyone who has worked hard in achieving this justice.”
