WASHINGTON (AP) -- A woman accused of plowing her car through a crowded street festival after a day spent smoking crack cocaine was ordered held without bond on Monday.

Tonya N. Bell, 30, is charged with aggravated assault, and prosecutors say they are considering additional charges. She is accused of driving through a police barricade into the crowd Saturday evening, sending people and strollers flying and injuring at least 40 people.

According to charging documents, Bell told police she had been "smoking crack all day." Her 7-year-old daughter was a passenger in a rear seat of the car, according to the documents. The child was not injured and was taken by Child Protective Services.

Officials were still waiting for toxicology results.

She previously served time in prison for charges involving cocaine, according to court records.

Bell had until recently worked in the office of Marion Barry, former mayor and a District of Columbia Council member, as a receptionist employed by a temp agency. Barry's office issued a letter terminating its contract with NAI Personnel.

In Barry's third term as mayor, he was videotaped in 1990 in a hotel room smoking crack cocaine in an FBI sting. He served a six-month prison sentence.
