As many as 13 liquor cases were seized from the house of Gian Singh, father of Akali councilor Rajinder Singh Virk, on Tuesday.
Incidentally, the bottles were seized a few days after the Patiala Urban bypoll, in which opposition parties including the Aam Aadmi Party had accused the Akalis of distributing liquor and money to woo voters.
The seizure has justified charges by opposition parties that the ruling party indulged in unfair means during campaigning. It has also fueled rumours that some Akalis had not worked in favour of party candidate Bhagwan Dass Juneja, and instead kept the freebies to themselves, said sources.
Akali councilor Virk had attacked AAP MP Dr Dharmvira Gandhi during the Lok Sabha elections and remained in jail, after being booked under section 307 of the IPC. He was later released on bail.
He is considered a close aide of cabinet minister Surjit Singh Rakhra.
Confirming the arrest, Sadar police station station house officer Charanjiv Lamba said they had registered a case against the accused under the Excise Act.
He informed the bottles of country-made liquor had been confiscated. Investigations in the case are on to find out where he bought it from.
