A wax figure of Adolf Hitler has been restored and returned to its display at Madame Tussaud's in Berlin after it was decapitated by a German man on the museum's opening day.

The figure was back on show Saturday and can be seen sitting at a desk in a replica of his Berlin bunker. Hitler committed suicide in the bunker in 1945 as the Red Army converged on Berlin.

Museum officials say visitors aren't allowed to enter the bunker area any more.

A 41-year-old man rushed the exhibit on opening day July 5 and beheaded the figure, shouting "No more war!" before he was tackled by security.

The wax Hitler had sparked a heated debate in Germany even before it went on display with critics and Jewish groups arguing that it was in poor taste.

Madame Tussaud's released a statement on Saturday saying the museum will not bend to pressure.

"As we've explained from the start, Adolf Hitler stands for a significant part of German history and his waxwork therefore is a legitimate part of our exhibition."

The 41-year-old, a former policeman, has since said he acted on a dare by friends and now regrets it.

He faces charges of causing criminal damage and bodily harm for injuring a security guard.
