Officials say a man has attacked Czech President Vaclav Klaus with a plastic gun, The Associated Press reported.

Presidential spokesman Radim Ochvat says Klaus was not injured in Friday's incident in the northern town of Chrastava where he was opening a new bridge.

Police spokeswoman Stepanka Zatloukalova says the man opened fire at Klaus from close range with a plastic pistol that uses small plastic balls as bullets. A 26-year-old man has been arrested.

Zatloukalova had no more details immediately.

It is not clear why the president's bodyguards did not intervene in time.
