In August 1999, Sixx and three of his band members were arrested in Las Vegas when authorities said Sixx was provoking a breach of peace at the Mandalay Bay Event Center. Police reported Sixx telling the audience, "If they don't like it, we can start flipping over cop cars like we did a couple of years ago." His band members, Chris Reynolds and Geoff Perren were both charged with obstructing a peace officer, and John Gabrielli was charged with battery on a police officer.
