LOS ANGELES  - Miami officials said on Friday reports of an arrest warrant issued for R&B singer Chris Brown are inaccurate, although the singer is still a suspect in the alleged theft of a mobile phone earlier this week. Brown, 22, who won a Grammy award earlier this month, is midway through a five-year probation after pleading guilty to criminal assault for beating ex-girlfriend Rihanna in 2009. If arrested again, Brown risks being jailed for probation violation. In a report filed with Miami Beach Police Department on Sunday, 24-year-old Christal Spann, a resident of Miami, named Brown as a suspect in a “robbery by sudden snatching.” The report cites Spann’s claim that Brown, who was in a black Bentley automobile, reached through an open window and snatched Spann’s iPhone out of her hand as she tried to snap a picture of him, saying “you ain’t going to put that on no website,” before driving off with the phone.
