Protesters call for another investigation into CzechTek police break-up

Some 300 people gathered on Prague's Kampa island to call for another investigation into the police break-up of last July's CzechTek techno music festival in west Bohemia. The protesters say not a single police officer has been charged, while 18 partygoers are being prosecuted. Water canon and tear gas were used during the operation, which left several dozen CzechTek visitors and police officers injured.
