Berlin police detained a 26-year-old Syrian man on suspicion of purchasing materials to make a bomb, federal prosecutors reported on Tuesday.
The suspect is also alleged to have sought information about bomb-making on the internet.
“The aim of his chat communications is thought to have been to prepare terrorist attacks,” federal prosecutors said after a police special unit had searched the suspect’s home in Berlin.
According to the federal prosecutors based in Karlsruhe, the man had begun “acquiring the components and chemicals for an explosive device.”
He bought acetone in August 2019 and a solution of hydrogen peroxide the following month.
“Both these chemicals are needed for making the high explosive triacetone triperoxide (TATP),” the Karlsruhe prosecutors said.
According to Berlin prosecutors, the suspect has since early 2019 been part of a messenger group seen as close to Islamic State and has exchanged information on making weapons and explosives.
The information concerned directions for making weapons and explosives, including plastic explosives and parcel and magnet bombs.
Information was also exchanged on assault rifles, submachine guns and other firearms.
