Chokechai police and soldiers were sent to the school to ensure peace and order.
The marching band, Max Percussion Theatre, had been the subject of heated debate since it pulled a publicity stunt asking Mr Tan, owner of Ichitan Group Co Ltd, for a 3.1 million baht donation to travel to a competition in the Netherlands from March 25-29. They won top prize in “Marching World Class” -- but were the only team in the category.
The band attracted harsh criticism for the way in which it “begged” the businessman for the money, then appealed for more cash from the private sector to travel to a separate competition in America.
