Fire in a flat after a battery explosion

A battery explodes and shortly afterwards the room is on fire. Every second counts for the firefighters to prevent the fire from spreading further. Then the next call: a car has crashed into a parked truck. The fire brigade is alerted in order to save the trapped passenger. The accident scenario is unusual. Was the cause of the serious accident possibly a street race? Psychological support can be found at wdr.de/k/psu-hilfe
