While Janet Jackson, 35, was playing to a packed house at Long Island, N.Y.’s Nassau Coliseum Wednesday night, her dressing room was broken into, reports The New York Times. Mario Backman was arrested and charged with burglary after he was discovered going through personal items belonging to the singer, Detective Lieutenant Kevin Smith, of the Nassau County Police Department, told the music Web site Launch.com. “At one point he made his way backstage, or into a back dressing room — which was actually her dressing room — and removed some personal items that included two stuffed animals, an FDNY baseball hat and some correspondence that was laying around,” said Smith. The New York Post identified Backman as a 19-year-old who lives in Manhattan’s Greenwich Village. “Apparently what happened was the victim’s manager apprehended Backman right at the scene, and he called police,” Smith told Launch.com. “That’s when we came in and we arrested him.” Backman was arraigned Thursday, according to Launch.com, which quotes Smith as saying that the suspect was charged with burglary, third degree, “which is a ‘D’ felony and, in terms of time that he could serve, it’s probably a maximum of three to seven years.” Jackson, meanwhile, continues her U.S. tour at Pennsylvania’s First Union Arena in Wilkes-Barre on Friday.
