The two, wearing only thong underwear and carrying inflatable dolls, were about to jump into the university's iconic Weiming Lake after the running prank. They were stopped by security guards, who were tipped off, and later taken away by police.

He Jie, who claimed to have been involved in the event, said the stunt was aimed at raising public awareness of music copyright protection.

He also said he and the other two are all alumni of Peking University and music lovers. They planned to make records after graduation two years ago, and the prevalence of music piracy forced them to organize this stunt, according to He.

The security guards received information about the event beforehand. Beijing News also received an email days ago detailing the time and place of the event.

A policeman said it is not illegal to wear thong underwear, but it was morally wrong.
