A former teacher has been jailed after admitting historic sex offences.

Roy Griffiths, 82, of Sherborne, admitted six indecency offences dating back to the 1960s.

At a hearing at Lincoln Crown Court the former Cathedral school teacher and boarding house master was jailed for six years and seven months.

Lincolnshire Police said the sentencing is the culmination of one part of the Operation Redstone enquiry into abuse at Lincoln Cathedral school in the 1960s.

The police investigation began in January 2016 after the safeguarding officer for the Diocese of Lincoln identified a previous concern from a former pupil of the Lincoln Cathedral school about the potential abuse of pupils by staff in the 1960s.

Officers from Operation Redstone spoke with the former pupil and began the complex task of trying to identify and locate pupils from the sixties - which was not straightforward as most of the records from the Cathedral school had been destroyed after it merged with others to form the Lincoln Minster School in 1996.

However more than 250 former pupils and their families and staff from Cathedral school were identified by the investigation team and most have been contacted including those now living in Australia, Canada, France, Poland and Spain.

Former teacher and house master at Cathedral school, Roy Griffiths, was traced to Dorset and arrested and interviewed in October 2016. He was bailed pending further investigation and then charged in April 2017.

On Friday, April 20, 2018 Griffiths admitted six charges of indecent assault on a male in relation to six boys under the age of 14 between 1963 and 1970. ​

Detective Superintendent Rick Hatton, senior investigating officer on Operation Redstone, said that Griffiths had shown no remorse for his actions.

“The nature of his offences has been devastating for his victims and their families,” Mr Hatton said.

“Today will be one step towards closure for the victims of the 13 offences he admitted to. The effects of the suffering of the victims from Griffiths’ abuse will probably never leave them but I hope the conclusion of this case today will assist them in their recovery.

"I want to pay tribute to the courage of those victims in being prepared to give evidence in court following our initial efforts to trace them.

“Our Operation Redstone enquiry into alleged abuse is continuing. I obviously do not want to undermine the integrity of the ongoing investigation so am not able to discuss it further at this stage.”

Any other former pupils or family members that wish to speak to the officers on Operation Redstone should contact Lincolnshire Police on 101 quoting incident 59 of April 20, 2018.
