The suspect, a 51-year-old employee of the BfV, or the Federal Office for the Protection of the Constitution, allegedly planned to bomb his employer’s headquarters in Cologne.
According to The Telegraph, German media reports that the suspect made a “partial confession” after being taken into custody.
An intelligence official speaking with Der Spiegel also indicated that the suspect shared “sensitive information about the BfV (Germany’s domestic security agency), which could lead to a threat to the office.”
A BfV spokeswoman similarly told the AFP that the suspect, who had been tasked since April with monitoring Islamist groups in Germany, had made “Islamist remarks online under a false name” and had offered “internal information during chats.”
