Passengers who managed to bring a speeding tram to a halt in Germany after the driver suffered a medical emergency have been hailed as heroes.
Panic spread through the tram as it sped through stations towards the western city of Bonn.
Two men smashed their way into the cabin of the driver, who was unresponsive.
A woman called the transportation company for instructions and the passengers brought the tram to a stop.
Prior to breaking into the cabin, terrified passengers called the Police and the emergency brake lever failed to stop the vehicle.
The local public transportation company SWB has defended itself as prosecutors investigate the incident.
