(UPDATED at 3:22 p.m.) An empty school bus believed to be on its way to Whitman High School this afternoon was involved in a three-car collision that left one person in serious but stable condition, according to a MCFRS spokeswoman.

MCFRS spokeswoman Beth Anne Nesselt said emergency personnel were called to the accident at the intersection of River Road and Whittier Boulevard shortly after 2 p.m. There, they extricated a person pinned in her vehicle. She was transported to a local hospital in serious but stable condition.

The bus driver was evaluated on the scene and did not require additional medical attention, Nesselt said. A third driver involved in the accident was transported to a local hospital for a check-up and evaluation.

As of 2:50 p.m., Whittier Boulevard was still closed at River Road, where police were managing traffic, Nesselt said. MCPS also sent supervisors to the area to assist with bus operations as Whitman and nearby middle schools were getting out for the day.
