A 61-year-old man was injured when a suspected country-made bomb planted beneath a parked vehicle at the collectorate-cum-district courts complex in Kollam on Wednesday.
Sabu, hailing from nearby Kundara, was standing near the vehicle belonging to the state labour department when the explosion occurred, police said.
Preliminary findings showed the explosion was caused by a ‘steel bomb’ (explosives packed in steel pipe) , police said.
Sabu suffered injuries in his eye and nose and his condition was not serious, police said adding he had been hospitalised.
Police suspect that explosive was deliberately placed under the jeep, which was not in use for a long time, so as to create a scare.
A bomb squad and other forensic officials are at the spot. Police said they recovered gelatin sticks and 17 batteries and fuse materials from the damaged vehicle.
