A teenage girl who acted as a youth Olympic ambassador has denied offences linked to rioting in London.
Chelsea Ives is charged with two counts of burglary, violent disorder and attacking a police car.
The 18-year-old, described as a "talented sportswoman", allegedly threw bricks at a police car during disturbances in Enfield, north London, on Sunday.
It is understood Ives was one of Waltham Forest Council's youth ambassadors who ensure young people's voices are heard and "have an input into developments for London 2012 and Paralympic Games", according to the council's website.
She took the role in 2008/09 and met London mayor Boris Johnson and Olympics chief Lord Coe.
A spokesman for the mayor of London said he had not yet recruited his London ambassadors for the 2012 Games.
Ives denied all four counts at City of Westminster Magistrates' Court. She was remanded in custody until next Wednesday, when she will appear at Highbury Corner Magistrates' Court.
