Calcutta, April 7: Truck drivers and operators today demanded security cover from police to move out of Indian Oil Corporation's bottling plant in South 24-Parganas, a day after a clash between two Trinamul unions stalled work at the plant. Around 180 trucks and 75 tankers have been waiting to leave the LPG bottling plant at Budge Budge, some 30km from Calcutta, since the clash yesterday.
