Leader of opposition Partap Singh Bajwa attacked the state Governnent over drug menace. He says it is seen whosoever raises question against the drugs in the state, he is punished by the state government. Take the case of Mohanjit Singh who raised a black flag when CM punjab was holding a public programme. Bajwa says he was being beaten by cops. Another case Gulzar Singh of district Sangrur was also pressurised and forced to commit suicide when he raised issue of drug menace before Punjab Finance Minister.. Bajwa says government has failed to control drug menace. He says we demand investigation in such cases but not from Punjab police but an independent probe should be conducted
