The German federal chief prosecutor has confirmed the arrest of a man suspected of planting explosives targeting the Borussia Dortmund team bus.
The incident occurred ahead of the first leg of a Champions League quarter-final between the Bundesliga side and Monaco on April 11.
Three explosions occurred as Thomas Tuchel’s team made their way to Signal Iduna Park for the European encounter.
Dortmund defender Marc Bartra was wounded by the blasts, with a decision taken to delay the fixture by 24 hours.
Authorities have now caught up with the suspect at the centre of the attack, with a 28-year-old man identified only as Sergei W taken into custody following his arrest by a tactical response team in the Tuebingen area on Friday.
He is a dual German-Russian citizen and is accused of attempted murder, inflicting serious bodily harm and causing an explosion.
A statement released by the chief prosecutor also revealed that the suspect had bought options on Dortmund’s stock before the attack, with it his intention to try and make a profit.
He is said to have purchased 15,000 contracts giving him the right to sell the shares at a pre-determined price.
“The accused bought 15.000 put-options regarding the shares of Borussia Dortmund on April 11,” a prosecutor’s statement read.
“Those options were running until June 17, 2017 and were bought with the ID of the hotel L’Arrivee (Dortmund’s team hotel).
“Someone who buys put-options speculates on the value of shares dropping. It allows the owner of these options to sell his shares until a certain date – in this case June 17 – to sell a fixed amount for a fixed price.
“If Dortmund’s shares had dropped in value massively, his profit would have been many times the investment. You could expect a massive drop in values of the shares if players had been injured or even killed during the attack.”
