Their motives for wearing the mankini in sub-zero temperatures have yet to become public but for the stunt an Astana court fined the six Czechs about $100 each.
Although some citizens of the Central Asian country found the story amusing, others took to the internet to vent their anger at the Czechs, with one posting on newtimes, a Kazakhstani news website, that the police "should have left them to freeze".
Another wrote that the "insolent foreigners should have been put in prison for 15 days."
Some of the anger aimed at the Czechs could stem from lingering resentment in Kazakhstan over the way the country was portrayed in the Borat film. According to Borat, the local wine, for example, is made from horse urine, and gay men have to wear blue hats.
At the time of its release in 2006 Kazakhstan banned the film and threatened to sue Baron Cohen, who had also written and produced Borat along with starring in it.
