Three people were hospitalized Monday night, including a child, after a multi-vehicle crash in the Gaithersburg area, Montgomery County officials said.

The accident happened in the 13400 block of Darnestown Road, where at least two vehicles collided and left one person trapped inside a vehicle about 10 p.m., said Pete Piringer, a fire department spokesman.

Rescuers had to extricate the adult from the car and transported that person to a hospital with serious and potentially life threatening injuries, he said. Medics also took another adult and the child with serious injuries to hospitals, Piringer said.

Police were investigating the cause of the crash.
