Harvard police and Cambridge paramedics yesterday removed a 20-year-old woman who had apparently overdosed on drugs from a Harvard shuttle bus that was parked in front of Currier House at about 10 a.m.

The woman, who hospital officials declined to identify, was taken by the paramedics to the Cambridge Hospital at 10:31 p.m., police said yesterday. The patient is in fair condition, a hospital spokesman added.

The driver of the shuttle bus, Millard P. Darden '82, said the woman had gotten on the bus at the Currier stop and had ridden the bus for the full loop. During the ride, the woman appeared not to know where she was going, and may have fallen from her seat, he added.

At the Currier stop, Darden and another passenger went to the back of the bus to see how she was doing, while a third passenger went into the building to call the police. Darden added that the woman could not move and was incoherent.

After the police talked to the woman and found that she had taken a prescription drug, they called the Cambridge Fire Department, the driver said. The paramedics removed the woman in a wheelchair, and took her to the Cambridge Hospital, a witness added.
