The city police on Monday arrested four persons as a follow-up to the raid on a luxury boat near Marine Drive a day earlier.
A party was going on in the boat on Sunday night when police seized 10 cases of beer and 10 gm of ganja. Police arrested three of the party organisers and the boat lessee under the Abkari Act.
The accused allegedly did not have the licence to serve liquor to customers. The accused were produced in court and remanded in judicial custody.
