Christian Horner's accuser has been suspended following Red Bull's investigation into "inappropriate behaviour" against the Formula One team principal.Horner, 50, was allowed to remain in his role after Red Bull Racing's parent company GmbH said last Wednesday that the grievance against him had been dismissed.The PA news agency reports that the complainant, an employee of the Milton Keynes team, has now been suspended on full pay.A Red Bull Racing spokesperson said: "We are unable to comment as it is an internal matter."Horner, who has always denied the claims made against him, is due to back in the spotlight in an official FIA press conference at 6:30pm local time (3:30pm GMT) in Saudi Arabia on Thursday.Following last weekend's season-opening race in Bahrain, Horner said he was "absolutely confident" he would stay on as Red Bull boss for the remainder of the season.
