Police are investigating damage to paintings stored at the castle in Valtice near Břeclav, the site of symposia since the mid-1990s until 2005. Some 50 works by contemporary Czech artists were apparently vandalised, either slashed or knocked out of their frames. The crime was only just discovered. Police also believe that some original works may also be missing. Works stored at the castle included a painting by tattooed composer and former presidential candidate Vladimír Franz.
