Investigators in Germany have found no indications of a "terrorist background" to the attack April 11 on the Borussia Dortmund soccer team's bus, the country's Federal Public Prosecutor announced Tuesday (via Deutsche Welle). 

Federal investigators have turned the case over to municipal prosecutors, saying the primary suspect apparently committed the attack "solely because of financial interests" and, thus, the multiple explosions didn't qualify as "a crime against the state of particular significance" that would make it the responsibility of federal prosecutors.

The suspect, a 28-year-old German-Russian arrested April 21, is accused of taking out a five-figure loan to short Borussia Dortmund stock, gambling that the value of the club would drop in the aftermath of what was disguised as an Islamic terrorist attack.

Dortmund defender Marc Bartra, who suffered a broken wrist and other injuries in the attack, returned to the team last week for the first time since last month's incident.

According to investigators, alleged plans found at the suspect's home included details on the detonators and remote control frequencies used in the attack that occurred as the team's bus was bringing it from its hotel to the home leg of its Champions League quarterfinal match against Ligue 1 club Monaco.
