The headmaster of a former Norfolk boarding school has been warned he could face a life sentence after admitting sex offences.
Bryan Greenhalgh, 63, from Suffield pleaded guilty at Norwich Crown Court to 13 counts of indecent assault and one serious sexual assault.
Charges related to eight boys at two former independent schools in North Norfolk and Lincolnshire.
He was remanded in custody and is due to return to the court on 23 May.
Judge Nicholas Coleman warned him he faced a “real risk” of a life sentence.
The offences were said to have taken place in the 1970s and 1980s at the former Sheringham Court School in Norfolk and the now-closed Thurlby Manor School in Lincolnshire.
DC Tristan Coull, of Norfolk’s child abuse investigation unit, said: “Greenhalgh is a dangerous individual.
“He exploited his position as headmaster to win over the trust of the boys in his care and subjected them to horrendous abuse.
“He clearly preyed on boys who were at their most vulnerable and who at the time of the abuse felt unable to speak out as he appeared to be an upstanding pillar of the community.
“Through the position he held, it would have been the most basic of expectations to protect these children, instead he chose to do the complete opposite.”
A second man, Ken Wells, 76, of Bracken Dale, Leicester, appeared in court with Greenhalgh and pleaded not guilty to one offence of gross indecency.
He was released on bail to go on trial on 9 June.
