NEW YORK - Foxy Brown pleaded not guilty Tuesday to charges that she threw a cell phone at a neighbor who complained about the volume of her car radio.

The plea to assault charges was entered on the 28-year-old rapper's behalf by her attorney, John Sampson, in Brooklyn state Supreme Court, the district attorney's office said.

Brown, who is serving a year at Rikers Island prison, arrived wearing casual street clothing.

She is in jail for violating probation -- skipping her anger management classes and traveling out of the city without permission -- in a Manhattan case involving a fight she had with manicurists in a nail salon three years ago.

Brown was arrested in the New York City borough of Brooklyn in August and accused of striking Arlene Raymond, 25, after the pair got into a fight July 30 over Brown blasting her car stereo near her home.

She was arraigned on charges of assault, attempted assault, menacing and criminal possession of a weapon -- the cell phone.

Justice John Ingram extended Raymond's order of protection to Dec. 18, 2008, and ordered Brown back in court on Dec. 17.

Sampson didn't immediately return a call for comment.

Last Friday, the entertainer twice refused to appear in court for her arraignment.

Prosecutors rescheduled her appearance for Tuesday, warning that if she refused to show up, the court would issue an order allowing correction officers to put her in handcuffs and force her onto a bus.

Brown, whose real name is Inga Marchand, has a new album, "Brooklyn's Don Diva," scheduled to be released Nov. 20.
