The Anti-Corruption Bureau (ACB) has registered an offence against a police constable in Maharashtra's Thane city for allegedly demanding a bribe of Rs 1.20 lakh from a person in exchange of not taking any action against him for selling gutka, which is banned in the state, an official said.

The case against the constable, who is attached to the Mumbra police station in the city, was registered under the Prevention of Corruption Act by the ACB's Thane unit on Wednesday, he said.
