Bangalore, Nov 09: In one of the biggest-ever such hauls here, the city police have seized a huge cache of explosives, arms, ammunition and chemicals used for making Improvised Explosive Device (IED) and arrested five men. The seizure yielded 1,200 electric detonators, 970 ordinary detonators, nine hand grenades, 13 empty pipe bombs, and 75 live rounds, apart from explosive materials, Karnataka home minister Mallikarjun Kharge told reporters here today. At least one of the accused was trained in handling explosives by PLOTE (People's Liberation Organisation of Tamil Eelam) in Tamil Nadu in 1985, he said but added that a probe was on to establish their links.
