Red Bull team chief Christian Horner was cleared Wednesday of wrongdoing following an investigation into complaints of inappropriate behaviour against him made by a female team member. A statement from Austrian energy drinks brand Red Bull, the parent company of the world champion Formula One team, said the "grievance has been dismissed". Horner, who has been team principal since 2005, denied the allegations made against him and was subjected to a lengthy interview by an independent London lawyer acting as investigator, who submitted a report to Red Bull.
