An ex-coach for some of Britain’s iconic Olympic superstars in the 70s and 80s has been found guilty of sexually assaulting a child.

Cyril Carter, 68, who worked in schools across south London, was found guilty of indecently assaulting a Kidbrooke schoolgirl in the 80s.

Carter had been a supply teacher in English and PE at Kidbrooke’s Thomas Tallis School when he met the youngster.

Speaking in court Carter’s victim told judge Ruth Downing that between 1983 and 1984, when she was 14 years old, the teacher repeatedly sexually assaulted.

After 23 hours the jury at Woolwich Crown Court was unable to reach a verdict on five counts brought against Carter and found him not guilty on two counts yesterday (November 29).

As a coach, Carter worked with Olympic heavy weights like swimmer Sharron Davies, judo Olympian Neil Adams and judo champ Brian Jacks, who achieved national fame on the BBC programme Superstars in 1979 and 1980.

Carter has also written books on the discus with British strongman Pete Tancred and judo techniques with Neil Adams.

Carter was arrested at Heathrow airport on June 28, 2014, after returning from Thailand.

He was found guilty of four counts of indecent assault which was reached by a unanimous verdict.

He will be sentenced on January 4 at Woolwich Crown Court.
