Former Hasmonean pupil has been jailed in the US for five years after he was found guilty of sexually assaulting children.

Miles Esterson, 28, was arrested in July in Florida, along with convicted sex offender, 45-year-old Jerry Wiley.

Esterson, who worked at Haberdashers' Aske's School for Girls in Elstree until 2008 and lived in Finchley, north west London, was found guilty earlier this month of performing sex acts on three boys under the age of 12 over the past two years.

Wiley, a registered sex offender, was sentenced to 10 years in prison. Esterson, a computer expert, had met Wiley, who ran a computer business, online.

Esterson pleaded no contest to lewd and lascivious conduct, a lesser charge that had been reduced from capital sex battery.

The boys, who were three brothers ranging from five to 11 years old, told investigators that the men, who were friends with their father, had molested them while on trips to Disney World and Sea World.

According to a search-warrant issued by Detective Chris Loyko, of the Lake County Sheriff's office, the children had been threatened to remain silent but one of the boys broke his silence when he returned home from visiting his father.

Esterson admitted that he paid for admission, travel, hotel rooms and other theme-park expenses for the boys and their father, and had taken them shopping.
