The Valhalla Fire Department was dispatched with Valhalla Ambulance Corps, Westchester EMS and Mt. Pleasant Police Department New York to a possible vehicle into the building with a party entrapped in the vehicle. Upon arrival crews found one vehicle off the side of a wall with one patient still inside. The vehicle did not strike the building but ruptured a gas line that goes into the building causing a gas leak. Command requested an engine from North White Plains Fire Company No. 1 for man power assistance. Crews stabilized the vehicle and removed the patient from the vehicle. Two other vehicles were heavily damaged by the wall falling on them. The patient was taken to the hospital for an evaluation. Crews remained on scene until vehicle was removed from the embankment by the tow.
