A Wiltshire nightclub has had its licence conditions tightened following concerns over anti-social behaviour.
Liquid and Envy, formerly the Brunel Rooms, must stop selling alcohol by 0200 GMT on drinks promotion nights.
Swindon Borough Council heard police concerns over the number of drink-related arrests on promotion nights.
The club's owner told the council's licensing panel that they have already taken security and training measures to reduce alcohol-related disorder.
The club's owners also have to ensure door staff are properly trained.
A police submission to the council raised particular concerns about Thursday nights at the club.
The club opens until 0300 GMT on Thursday and has later hours for Friday and Saturday events.
Police said the club, which can have about 2,500 customers a week, is linked to 17% of alcohol-related arrests in the town.
