German police said Sunday that they had detained a male suspect in his 20s after an attack threat against a night club in Offenburg appeared online.
Police launched a major operation in the southwestern German town on Saturday night, upping security in the town center, the main train station and on the border with France. Security was particularly tight around Offenburg’s night clubs and one was cleared out by authorities.
“A dance club in the industrial area was evacuated in the early morning hours for security reasons,” police said in a statement. They did not name the club that had been threatened.
