A FORMER teacher from North Dorset has admitted charges of sexually abusing six young boys.

Roy Griffiths, 82, from Sherborne, who taught at the Lincoln Cathedral school in the 1960s, was due to stand trial but admitted the charges at Lincoln Crown Court.

He was arrested as part of Operation Redstone, an investigation into complaints of sexual abuse against members of the clergy and teachers.

Lincolnshire Police said its Operation Redstone inquiry followed a review of past safeguarding cases by the Diocese of Lincoln.

Griffiths was granted bail to appear for sentence on April 20.

He admitted six charges of indecent assault which relate to offences between January 1963 and July 1970 and involved six different boys.

Judge Simon Hirst ordered Griffiths to be placed on the sex offenders register.

He said: "You have pleaded guilty to serious offences committed at a time when you had a high degree of trust placed in you.”

The judge said he was prepared to adjourn for the preparation of a report but warned Griffiths that a custodial sentence is “almost inevitable."
