A cathedral worker subjected a 13-year-old schoolboy to a series of sexual assaults, a court heard today.

Terence Banks, 62, whose father was the treasurer at Chichester Cathedral, first indecently assaulted the boy during a day out water skiing, Lewes Crown Court was told.

The former BBC production worker, who helped run the Cathedral's annual festival, then grabbed the boy at his father's house as he took a bath.

Banks, who had a flat in Hammersmith, London, denies a charge of seriously sexually assaulting a boy under 16 between January 1 1971 and December 31 1973.

He also denies a serious sexual assault between August 16 1975 and August 15 1978, a charge which relates to a second boy.

Philip Katz, prosecuting, told the court Banks ran an organisation called the Crudgemen Group which helped stage the cathedral festival, held each year in July.

Mr Katz said Banks, who acted as a steward during cathedral services and at coffee meetings afterwards, indecently assaulted a 13-year-old in summer 1972 while on a water skiing trip to a gravel pit near Chichester, and at Banks' father's house in the city's Cathedral Close.

The second alleged victim, who was 14 at the time, was allegedly attacked at the cathedral worker's London flat in 1975, the court heard.
