German police, investigating the bombing that targeted Borussia Dortmund football team on Tuesday night, are looking for possible Islamic extremist links after they found a letter that carried a reference to Germany’s anti-Islamic State operations in Syria. A German news agency, however, reported that the explosions were carried out by an anti-fascist group in response to the club’s “alleged tolerance for racists and right-wing fans.”
Amid conflicting claims about who is behind the attack, German federal prosecutors, who specialize in terrorism-related cases, took charge of the investigation, writes the BBC. Newspaper Sueddeutsche Zeitung suspected that the letter could have been deliberately planted at the site to mislead the investigation.
Without revealing the details of the letter, German police said they are verifying its authenticity, notes The Guardian. The explosions sparked panic among the players and the supporters in the stadium before they were safely evacuated and the match postponed.
