Police are probing the possibility that the object used in the Saturday attack on Prime Minister Fumio Kishida could be a homemade pipe bomb, investigators said Sunday.
The revelation came as police raided the home of Ryuji Kimura, the 24-year-old suspect, in Kawanishi, Hyogo Prefecture, in the early hours of Sunday.
Conducting wires found on both ends of a second cylinder found at the scene, which resembled a steel pipe, led investigators to believe it was a pipe bomb, as such devices have gunpowder sealed inside a cylinder which is detonated by igniting a fuse, NHK reported.
