Madame Tussaud's wax museum has now grown to become one of the major tourist attractions in London, and has expanded with branches in Amsterdam, Hong Kong (Victoria Peak), Las Vegas, Shanghai, Berlin, Washington D.C., New York City, and Hollywood. The current owner is Merlin Entertainments Group, a company owned by Blackstone Investment Group LP.In July 2008, Madame Tussauds' Berlin branch became embroiled in controversy when a 41-year old German man brushed past two guards and decapitated a wax figure depicting Adolf Hitler. This was believed to be an act of protest against showing the ruthless dictator alongside sports heroes, movie stars, and other historical figures. However, the statue has since been repaired and the perpetrator has admitted he attacked the statue to win a bet.The original model of Hitler, unveiled in Madame Tussauds London in April 1933 was frequently vandalised and a replacement in 1936 had to be carefully guarded.
