Brown and the 'Umbrella" hitmaker reportedly got involved in a heated argument over a text message from other woman after the pre-Grammy party, which led to the alleged scuffle.
According to the experts, the accused might have banged the victim"s head against the car window, bit her ear and fingers and got her in a headlock until she began to black out, eventually forcing her to try to gouge his eyes to make him let go.
While one of America"s top crime scene experts made a CSI-style analysis of pictures of the Lamborghini and found “clear signs" of a fight, experienced former New York cop Hal Sherman revealed blood around the car"s handbrake, smears and fingerprints on the control console and a snapped-off cigarette lighter all suggested that the passenger had been dragged across the seats by the driver.
“What I saw is indicative of the passenger being beaten by the driver," The Sun quoted Hal as telling Us magazine. Brown recently appeared in court and was freed on 35,000 pound bail until a hearing on April 6. The court also ordered him not to “harass, threaten or use force" against anyone, but did not order him to stay away from Rihanna.
Meanwhile, Brown and Rihanna are said to have made up and reunited at P. Diddy"s Miami home last week.
