San Francisco – Nieka Arreola certainly lived up to her last name when cops discovered the 30-year-old San Francisco schoolteacher naked in a car with an unidentified minor. Arreola now faces lewd conduct charges in an incident involving a 14-year-old Luther Burbank Middle School student, authorities said.

At 5:30 p.m. Thursday, patrol officers driving in an area of McLaren Park known for drugs and prostitution spotted a car with steamed windows, suggesting either drug or sexual activity, according to Capt. Frank O’Malley of the Police Department’s Juvenile Division.

Upon checking the car, which was parked at John F. Shelley Drive and Cambridge Street, officers found Arreola and the unidentified student, who worked as an aide in a classroom at Luther Burbank, undressed in the car. Arreola reportedly told police she was giving the boy a ride home. She was booked on three counts of lewd and lascivious acts on a minor.

The school district has started its own probe in the wake of the arrest.

“The school district is shocked and saddened by the allegations,” according to a statement issued by Roqua Montez, district spokesman.

Montez declined to discuss the employee’s assignment. However, according to the district’s Web site, in October Arreola was named lead teacher in the after-school program at Burbank.

Montez said Arreola had been ordered not to come to work pending completion of the investigation. He could not say whether she had actually been suspended or how long she had been employed by the district, citing confidentiality rules.

“We are highly alarmed about this case — we are investigating the depth and scope of this particular matter,” Montez said.

He said that parents, teachers and administrator had been notified Friday of the incident. He said resource counselors would be on hand Monday to assist students and faculty.
