Taking place in a meadow next to the D5 motorway near Mlýnec in the Plzeň Region, the festival was raided the following day by riot police using heavy equipment including tear gas, water cannons and military BVP vehicles.

Czech president Václav Klaus criticized the police's use of heavy force, while Prime Minister Jiří Paroubek defended it.

[6] CzechTek 2005 was a smaller festival than previous years, attended by around 5,000 people, with just a few sound systems playing on the night from Friday to Saturday.

According to the final report of the Plzeň Regional Rescue Service, many other injured participants of the techno party may not have sought medical treatment at the scene, and the number of injuries was therefore probably higher.

The police intervention was widely criticised by the participants, sympathetic sections of the public, and some politicians, who said the response was disproportionately harsh, and in violation of the law and human rights.

The Czech president Václav Klaus criticized the police's use of heavy force, and the Senate called it unreasonable, while Prime Minister Jiří Paroubek, defended the action, declaring that the tekno fans were "not dancing children but dangerous people".

[12] Minister of the Interior František Bublan called for stricter legislation to prevent similar events from taking place in the future, but it was rejected.

In 2009, the attack on CzechTek was cited as one of the causes of the youth protests against Jiří Paroubek and ČSSD during the European Parliament election campaign.
