The excise department will conduct a probe to find out whether the liquor served at the Saturday night party at The Park, from where 37 people were arrested for violating Covid norms, was provided by the hotel or not.

The decision was taken on Wednesday, a day after the excise department barred the hotel from serving liquor in all its 10 bars and rooms till further notice.

The probe will run parallel to the one that is already being carried out by the detective department of Calcutta police.

The excise department will set up a team that will visit the Park Street hotel within the next few days.

“The team will talk to hotel officials and find out how liquor reached the revellers beyond the stipulated time of 8pm on Saturday,” said a senior officer of the excise department. “We will then scan the seized liquor bottles.”

Following the findings of the probe, the department would invite the hotel authorities for a hearing and a final decision would be subsequently taken on whether the restriction on serving liquor would remain or not.
