An Islamic State (IS) flag was discovered near a damaged overhead power cable on a Berlin railway track, according to German police.
Leaflets in Arabic were also found and authorities are investigating if the propaganda is related to the apparent sabotage.
“Since the beginning of the investigation, several pieces of evidence have been secured,” said police.
Additionally, a torn steel cable was found at the scene of Sunday’s suspected attack on the tracks.
Given the possibility of this being a terrorist attack, federal police have taken over the investigation to officially deduce any "political motivations" linked to the findings.
Correspondingly, in October, German authorities discovered a threatening letter written in Arabic alongside mangled steel cables that were stretched across the tracks of a high-speed railway line between Nuremberg and Munich.
As of this writing, it is unclear if the two incidents are connected.
