The incident occurred on Sunday evening after two people asked the bus driver for a cigarette.

When the driver refused, he was threatened with what appeared to be a handgun. He was however able to get to safety and alert the police to the attackers.

Both men were apprehended soon after in rue du Fort Niedergrünewald. It turned out that the handgun was in fact an air pistol, but that they were also carrying a real knife. The attackers received a fine.
