A Jeep slammed into a Rockville office building on Wednesdsay, plowing all the way through an office and coming to rest in an atrium about 25 feet into the building. No one was injured.

Montgomery County Fire and Rescue Service spokesman Pete Piringer said that the Jeep first backed into a parked Mercedes in the parking lot of the office building on Research Boulevard. Then it hurtled forward, charging through the ground-floor office space occupied by Hearing Healthcare Inc.

Piringer said that a person had been in the space that the Jeep zoomed through just before the crash, but fortunately no one was in the way when the vehicle came through the wall. Some workers in the adjacent office were trapped. Firefighters got them out, as well as the driver of the Jeep, who was also trapped in her car by debris.

Rockville police are investigating the cause of the crash.

Piringer noted that everything worked out as well as it could have, in what might otherwise have been a dangerous situation. Rescue workers were able to isolate the utilities to avoid a fire or gas leak. The car did not hit any of the building’s structural support. The building was briefly evacuated, then occupants were able to return to every office but the one that the Jeep had driven through.
