According to a source, the criminal investigation was initiated when a judge unsealed depositions in a civil case filed by a woman, TMZ.com reported.

Meanwhile, another woman from New York has claimed that the American comedian assaulted her during the 2004 Penn Relays track meet in Philadelphia by grabbing her from behind and forcing her backside into his private area. She says she immediately complained but event officials blew her off.
