Bellandur police discovered a bunch of gelatin sticks and an electrical detonator stored in a box in a tractor parked at a labour shed opposite a school at Chikkanayakanahalli in Bengaluru on the night of March 17.
Police Sub-Inspector Revannsiddappa alerted his senior before seizing the material and registering an FIR against the owner of the tractor under the Explosives Act and Section 286 (negligent conduct with respect to explosive substance) of the Indian Penal Code.
The initial probe revealed that the explosive material was in violation of licencing conditions and negligence in the way it was stored, a police officer said.
