Around 40,000 at this year's CzechTek free music festival

Around 40,000 people from the Czech Republic and elsewhere in Europe have gathered at the CzechTek free techno music festival, which is being held on Czech Army land in north Bohemia. Last year's CzechTek became the subject of political debate when around 1,000 riot police used truncheons, tear gas and water cannons to break the festival up, after complaints from landowners.
