German media reported on Sunday that authorities in the state of Bavaria were investigating a possible attempted terror attack on a high-speed train. The incident, according to the Bild daily, involved a steel wire being pulled across the tracks.
On October 7, a conductor on a train heading south from Nuremberg and Munich heard a strange sound he attributed to a small technical glitch on the train.
Later, however, police found the wire that was stretched across the train's path and wooden wedges were placed on the tracks.
According to Bild, authorities are also in possession of a threatening letter in Arabic, which promises more attacks, and the incident occurred near a bridge with Arabic graffiti.
The newspaper did not, however, clarify if that was connected to the attempted attack on the train.
