A report in this regard was submitted to the government by Additional Director General of Police (Intelligence) A Hemachandran, who has also asked the Excise and other enforcement departments to enhance vigil.
There was a possibility that people who were aggrieved by the new liquor policy might try to exploit the situation and create trouble, the report said.
There were chances of spurious liquor being sold in festival places and tourist spots in the state, it said.
