FUKUI – Police seized six homemade bombs Monday from the home of a 33-year-old Fukui man who was critically injured when one of the explosives blew up prematurely.
According to police, the explosion took place at around 5:30 a.m. Sunday in a parking lot beside a building that served as a pharmacy and residence.
Shrapnel scattered as a result of the blast and a wall of the building was charred, police said.
The man, whose identity was not disclosed, was quoted as telling investigators who arrived at the scene that the bomb was hand-made and that he learned how to make the explosive s via the Internet. Police said it appears the man made a mistake when handling the timing device. He was hospitalized with serious burns over his entire body.
A police search of the man’s house turned up six explosive devices — three made from fire extinguishers, two from steel pipes and one from a bicycle pump, investigators said. They also found several fire extinguishers that appeared to be in the middle of being transformed into bombs.
These were frozen and removed from the house, and residents in the vicinity who were ordered to stay away were able to return to their homes at around 1:45 p.m.
The man was quoted as telling police that the pharmacy was the home of a high-school classmate who had bullied him, and that the attack was planned as retaliation. However, sources close to the people residing in the building said they had no idea why he bore a grudge against them.
A search of a car rented by the man late Saturday afternoon turned up two other explosives that were crafted from fire extinguishers, and residents within a 10,000-sq.-meter area were ordered to evacuate while a police bomb squad removed them.
Police later said they also found a plastic tank containing a gasoline-like liquid.
Once the man’s condition improves, police will interrogate him, investigators said.
