NAGOYA -- A university student was arrested on Aug. 20 on suspicion of creating high level explosives of the same type as those apparently used in terrorism attacks overseas and setting off a blast at a local park, police announced.
The 19-year-old man, a resident of Nagoya's Midori Ward who stands accused of violating regulations including the Explosives Control Act, has apparently admitted to the allegations. He was quoted as telling police that he knew the explosives had been used for terrorism in the past and said, "I wanted to test the power of the explosives."
The man is suspected of creating 57 grams of acetone peroxide (TATP) at his home at the time in Nagoya's Meito Ward on Dec. 22, 2016, and detonating black powder at a park in the same ward at around 8:30 p.m. on March 19, 2018. In addition, he allegedly created another 9 grams of the highly explosive erythritol tetranitrate (ETN) on Feb. 11, 2017.
Following the March 19 blast, pedestrians and residents around the park reported the incident to police at around 8:45 p.m. Police officers questioned the suspect, who was then a third-year high school student, but did not arrest him at the time.
