The cops apparently left no stone unturned while investigating Chris Brown.
E! News has learned exclusively that, among the evidence turned over to the Los Angeles District Attorney's Office for its probe into the singer's alleged attack on Rihanna, is a bloodstained Gucci gown identified as the one Rihanna was wearing when they fought on the morning of Feb. 8.
"The police took Rihanna's dress into evidence because it had bloodstains on it," says a source close to the investigation. An LAPD spokesman tells E! News, "We don't comment on domestic violence cases."
The $11,000, flowing strapless gown was provided to Rihanna by Gucci, with whom she has a multimillion-dollar endorsement deal, for Clive Davis' annual Pre-Grammy Gala at the Beverly Hilton, where she and Brown were spotted looking cozy the evening of their altercation.
E! News also has learned that, just hours after the alleged attack, the LAPD filed an emergency protective order—at Rihanna's request—barring Brown from having contact with the "Umbrella" songbird. The order expired five days later, according to sources.
"It is standard practice for the cops to ask the domestic-violence victim at the scene of the attack whether they would like an emergency protective order keeping the attacker away," Santa Monica-based criminal defense attorney Alec Rose tells E! News.
"If the victim requests it, the EPO is issued and is good for five days. After that time period, the victim would have to notify the District Attorney's Office if they would like the order extended."
