Acting on a tip off, a joint team was constituted with police and excise officials which raided a saw mill at Tengrari village under Minapur police station late last night.
The joint team seized the 335 liquor cartons, hidden under 550 packets of biscuits and clothes in a truck, bearing a Punjab registration number.
The driver of the truck from which the liquor cartons were seized, was among those arrested, Excise Superintendent Deenbandhu said.
The Nitish Kumar government had in April 2016 enacted a stringent anti-liquor law banning manufacture, bottling, distribution, transportation, accumulation, possession, purchase, sale or consumption of liquor in Bihar.
