Four people teamed up to rob the racy rapper of a Louis Vuitton bag, $500 in cash and credit cards around 5:30 a.m. Saturday in Brooklyn, police said.
Roshawn Anthony, 23, was arraigned Sunday on charges of robbery, assault and grand larceny, said Clinton Hughes, an attorney with Legal Aid who is representing Anthony.
"She denies these charges," Hughes said.
Bail was set at $50,000 and her next court date was Thursday.
Brown's lawyer, state Sen. John Sampson, did not immediately return telephone and e-mail messages early Sunday. But Brown told the New York Post that the robbery never happened, and that she hadn't been at the location police gave, near a public housing complex.
"A lot of the time, people mistake me for someone else, or people always call in these false tips," Brown told the newspaper outside her Brooklyn brownstone Saturday.
Police said the rapper, whose real name is Inga Marchand, had indeed been attacked.
Brown, 27, is known for her sexy outfits and steamy lyrics. Her albums include the platinum-selling "Ill Na Na" and "Chyna Doll."
She pleaded guilty in August 2006 to misdemeanor assault charges stemming from a fight with salon workers over payment for a manicure in Manhattan's Chelsea neighborhood on Aug. 29, 2004. She was sentenced in October 2006 to three years' probation.
Brown was charged with battery and resisting an officer with violence in Florida on Feb. 15, when police said she threw hair glue at a beauty shop employee when he asked her to leave because the shop was closing. That case is pending.
The Florida case also brought more legal trouble in New York for Brown. She pleaded guilty in March to a probation violation for leaving New York without permission.
