Hove student Charlie Gilmour – son of Pink Floyd guitarist Dave Gilmour – has appeared before a court in London after the student protests in December.
Gilmour, 21, was charged with violent disorder when he appeared before magistrates.
The Cambridge University history student was pictured hanging a flag from the cenotaph and accused of stealing a mannequin from a shop in Oxford Street.
The theft charge was dropped but Gilmour, son of the novelist Polly Samson, was charged with being part of the mob which attacked the convoy of cars carrying the Prince of Wales and the Duchess of Cornwall.
Gilmour is said to have sat on the bonnet of a car carrying royal protection officers in Regent Street.
The car was one of three in a convoy taking the prince and the duchess to the Royal Variety Show at the London Palladium near by.
Gilmour is also said to have thrown a rubbish bin at the convoy, hitting one of the vehicles, although but not the car carrying the royal couple.
District Judge Daphne Wickham granted Gilmour bail at the City of Westminster Magistrates’ Court.
He must return to the court on Friday 25 March.
