DORTMUND: German police have arrested a 28-year-old man suspected of being behind last week’s attack on the Borussia Dortmund team bus hours before a Champions League quarter-final against Monaco.

Greed, not ties to international terror, is thought to have motivated the suspect.

Germany’s Federal Criminal Police and the Federal Prosecutors Office have confirmed the arrest, which took place in the southern German city of Tübingen.

The suspect, identified by the media as Sergej W., and holding both Russian and German nationalities, was reportedly staying at the team’s hotel on the day of the attack.

His room provided a view of the street where the explosion by three explosive devives loaded with metal shards and nails injured Dortmund player Marc Bartra and a police officer.

Authorities had begun investigations against the 28-year-old suspect, late last week on 20 counts of attempted murder.

The suspect allegedly bought options to short sell 15,000 shares of Borussia Dortmund stock for €78,000 according to local media. He would have profited from the transaction if the price for shares of the club fell.

The share price did fall from €5.738 to a low of €5.421 after the attack. Having recovered slightly after the attack, the share price slid again, closing yesterday at €5.395 after the club’s exit from the Champions League.
