In a possible breakthrough in investigations into the crude explosive found in the Kingfisher aircraft, police tonight took one person into custody for questioning based on the marking on the newspaper in which the bomb was wrapped.
Police sources said the suspect was taken into custody at Nedumangad Town near here while they were pursuing a lead in the form of markings in the Malayalam newspaper in which the crude device was found wrapped yesterday.
The Thiruvananthapuram edition of the Malayalam newspaper had an "N" mark on it which indicated it was distributed in Nedumangad area, about 25 km from towards the eastern side of the state capital.
Since last night, police had been questioning newspaper agents and vendors in the area in this connection, the sources said.
Meanwhile, the FIR lodged in the case said the substance was not of high intensity.
According to the FIR, based on the forensic analysis of the material, the material was a mixture of potassium chloride, ammonia and sulphur.
Though the crude device could not go off on its own, the possibility of it bursting due to air pressure during flight could not be ruled out, the FIR, said.
