The Palace Museum clarified rumors about a security guard beating a tourist at the museum in a statement issued on Wednesday.

A video was posted online on Monday showing a man tussling with several security guards in the museum square. The video was reposted on several major video websites.

The museum said in its statement that the man was an illegal tour guide who has been selling illegal tours of the museum for years with his sister. The two have been punished by the police several times.
