Under-fire Australian Olympic Committee spokesman Mike Tancred stands down pending bullying investigation

Under-fire Australian Olympic Committee media director Mike Tancred has stood down from his post pending the outcome of bullying and harassment claims made against him.

The AOC released a brief statement on Wednesday saying Tancred is “standing down from (his) position of AOC Director of Media and Communications pending the outcome of any investigation of the complaint made against (him) by Fiona de Jong.”

De Jong has served as chief executive of the AOC and is one of what’s believed to be a host of bullying and harassment claims made against Tancred.

She recently alleged that Tancred that made serious threats against her.

"He said 'Fiona, withdraw the complaint or I will bury you'," de Jong told Fairfax Media, adding the long-time media director was "abusive and threatening to me and would have affected my family life".

Tancred on Wednesday rejected de Jong's claims.

"I deny all the allegations made against me," he told AAP.

"I have made no comment to any of the allegations because I am bound by a confidentially agreement which I signed.

"Ms de Jong also signed that agreement but breached it over the weekend."

The AOC board will meet on Wednesday night to discuss the latest developments.

The situation involving Tancred comes amid a power struggle for the AOC chair.

John Coates, who has served in the role for 27 years, is facing a challenge from former Australian hockey representative Danni Roche.
