A police officer has denied assaulting a female protester during the G20 demonstrations in London.
Sgt Delroy Smellie, 47, of Clapham, south London, pleaded not guilty to common assault at City of Westminster Magistrates' Court in central London.
Prosecutors allege he struck Nicola Fisher, 35, of Brighton, at a protest in Royal Exchange Square on 2 April.
Sgt Smellie was released on unconditional bail and a trial date has been set for 22 March 2010.
The officer wore a dark suit and mauve tie for his court appearance.
The alleged incident took place on the second day of the G20 protests, which were held to coincide with the gathering of world leaders in the city.
Newspaper seller Ian Tomlinson had died during the previous evening's demonstrations and Ms Fisher was among a large crowd who attended a vigil for Mr Tomlinson.
