A renowned figure skating coach who has mentored Olympic and world champions has been suspended by US Figure Skating, the organisation said.

Richard Callaghan, 72, is barred from any figure skating activities pending a fresh investigation into decades-old allegations of sexual misconduct.

When several male skaters levelled their accusations in the 1990s, the veteran coach “vehemently denied” them.

A watchdog to prevent sexual abuse of athletes will investigate the case.

“US Figure Skating suspended the membership of Richard Callaghan on March 6, 2018, in compliance with the policies and procedures of the US Center for SafeSport,” the sport’s governing board said in a statement on Friday.

Mr Callaghan told ABC News he had not been officially notified of the suspension. He also declined to speak about the allegations.
