Police have refused to comment.
A centuries-old May Day tradition ended in tragedy on Monday when a 20-year-old man was killed by a falling maypole after he and other youths from a neighbouring village cut it down.

People of all different political persuasions have been attending a series of May Day rallies in towns and cities across the country. In Prague's Letna Plain, a large open-air space where the Communist Party have traditionally held their rallies, several thousand people attended a large anti-Communist gathering.

In other news, the Czech Trade and Industry ministry says the South Korean car-maker Hyundai still intends to go ahead with a new assembly plant in North Moravia despite the arrest last week of the company's chairman Chung Mong-Koo on embezzlement charges. Minister Milan Urban said the signing ceremony would now be held in Seoul, and not the town of Nosovice, where the one-billion-plant will be built. Mr Chung and Hyundai are accused of creating slush funds to pay politicians and officials for business favours.
After being denied their traditional venue, the Communists - who are currently in opposition - held their rally in Prague's 19th century Vystaviste exhibition grounds.

Also attending was Milos Jakes, leader of the totalitarian Communist Party until 1989, and Jiri Dolejs, the party's deputy leader who was beaten up last week in what he said was a politically-motivated attack.

In the second accident in eastern Bohemia, the coach driver fell asleep and the vehicle overturned into a ditch. Seven passengers were injured; two of them are still in hospital.
Water levels of some rivers in Moravia have risen extensively following heavy rain on Saturday. Some areas in southern Moravia were put on the highest degree of flood alert.
