Brown's arraignment was postponed until April 6 on charges of assault likely to cause great bodily injury and making criminal threats. The 19-year-old R&B singer remains free on $50,000 bail.

Details released Thursday offer a starkly different portrait of Brown than the squeaky-clean image he has cultivated. The young man once praised for his Michael Jackson-esque dance moves is described in a detective's affidavit as punching his girlfriend, biting her ear and trying to choke her until she nearly lost consciousness. -
