A former boarding school teacher has pleaded guilty to indecently assaulting three 10-year-old boys over a five-year period.
David Dean was warned he would face jail for the attacks, which he admitted took place at a school in Kent between 1978 and 1983.
The 58-year-old, who now lives on the Isle of Wight, pleaded guilty to five out of nine counts of indecent assault at Canterbury Crown Court.
The case had to be delayed on Monday after he suffered a suspected heart attack, which turned out to be a panic attack.
'He abused trust'
Dean, from Totland on the Isle of Wight, was a master at Vernon Holme School in Canterbury where the offences took place.
Prosecuting solicitor Robin Johnson told the jury: "The abuse included touching children indecently and forcing one to perform oral sex."
He was a manipulative, predatory paedophile who parents had entrusted the safety of their children to
After pleading guilty, Dean told the court he had felt a great deal of shame over what he had done for more than 20 years.
Judge Anthony Webb ordered the four counts to which Dean pleaded not guilty to be left on file.
Dean was granted bail ahead of sentencing on a date next month, yet to be fixed.
But the judge warned him to expect to be sent to prison.
Detective Sergeant Steve Woollcott, an officer in the case said after the trial: "He was a manipulative, predatory paedophile who parents had entrusted the safety of their children to.
"He abused that trust, assaulting these vulnerable children."
