One of the two suspects in Tuesday’s attack that left a Borussia Dortmund player injured was arrested, German federal prosecutors announced on Wednesday.

Prosecutors said the two suspects have Islamist links, and authorities sought a warrant for the other individual thought to have had a role in the three explosions --- which included metal strips to inflict more damage --- before a UEFA Champions League soccer quarterfinal between Borussia Dortmund and AS Monaco.

Defender Marc Bartra fractured his wrist in the attack. Two letters taking credit for the attack were being examined by German authorities, although prosecutors said they have “considerable doubts” about the authenticity of one of the letters that came from a left-wing extremist group.

Police said the explosions occurred shortly after 7 p.m. local time Tuesday and the game was postponed. The game was rescheduled for 6:45 local time (12:45 p.m. ET) on Wednesday.

Officials announced that backpacks would be banned, and fans were encouraged to arrive to the stadium early.

“We do not just play for us today,” Borussia Dortmund chief executive Hans-Joachim Watzke said (per BBC). "We play for everyone -- no matter whether Borussia, Bayer or Schalke supporters. And of course we play for Marc Bartra, who wants to see his team win."
