A retired teacher who admitted a catalogue of sex abuse crimes against young boys dating back nearly 50 years will be sentenced today.
Christopher Jarvis, 70, pleaded guilty to 14 charges of indecent assault and gross indecency on 10 boys aged from 10 to 14 between 1964 and 1976.
Jarvis' victims were pupils at the now-defunct St Peter's Preparatory School in Seaford, East Sussex, the former school of the Archbishop of Canterbury, Justin Welby.
Jarvis taught at the school between 1962 and the early 1980s when it closed. He was arrested after one victim came forward for the first time in late October last year, Sussex Police said.
Jarvis was detained on November 5 and further inquiries resulted in more victims coming forward. He was eventually charged when he answered police bail on June 3.
Detectives said Jarvis used his position of trust to groom young and vulnerable boys who were powerless to prevent him abusing them.
They said the victims showed great courage by reliving their ordeals, and that the passage of time had not prevented Jarvis being brought to justice.
Detective constable Hannah Elmer, of Sussex Police, said: "During his time there he targeted young and vulnerable boys who were powerless to say no to him.
"He systemically groomed each of his victims, becoming someone who they liked and trusted. He was then able to use this, and his position as a teacher, to his advantage by getting the boys on their own and sexually abusing them.
"This was a complex and distressing case during which each victim showed great courage in coming forward and re-living events which had occurred many years before.
"Thanks to their strength we have been able to investigate this to a positive outcome and have provided many others with some form of closure. This investigation shows that all such incidents, no matter how historic, can be investigated and justice served."
Police said there was no evidence to suggest any children have been recently or currently at risk. Jarvis, who has been remanded in custody, will be sentenced at Hove Crown Court.
