A 28-year-old German-Russian national has been arrested on suspicion of attacking the Borussia Dortmund football team with three homemade bombs.
German police detained the suspect — named only as Sergei W. — in the Tuebingen area of southwest Germany on Friday morning, the Associated Press reported.
They believe he detonated three bombs alongside the Borussia Dortmund tour bus on April 12 as it traveled to a Champions League match against AS Monaco.
Defender Marc Bartra and a police officer traveling with the team were both injured in the attack.
Despite early concerns linking the attack to terrorist groups, investigators now say that the attack was financially motivated.
Prosecutors claim that the suspect had bought a large number of put option shares in Borussia Dortmund, guaranteeing a set price for the shares if he wanted to sell them later.
If the value of the shares dropped dramatically, however — as the result of a terrorist attack, for example — he would have stood to make a substantial profit, police said.
The man faces charges of attempted murder, causing an explosion and serious bodily harm.
