Police have seized more than 150 cases of beer, 50 cases of wine and 141 bottles of spirits, following a search of a commercial building in Belfast's Ormeau Road.
The quantities of alcohol were seized after a search took place on St Patrick's Day following concerns around "the potential illegal sale of alcohol" in the area.
Police seized the goods under the licensing order after having obtained a warrant and undergoing a search of the premises.
In a statement, PSNI Chief Inspector Gavin Kirkpatrick said: "Our licensing officer working alongside our City Centre Neighbourhood Policing team obtained a warrant and carried out the search, locating 176 cases of beer, 50 cases of wine, 141 bottles of spirits, 72 litres of cider and 76 bottles of alcopops, which we suspect were being sold locally illegally.
"While our investigation into this matter is ongoing, one male was cautioned for the offence of selling intoxicating liquor without a license.
"We regularly respond incidents involving noisy parties, drinking in public spaces and anti-social behaviour, and often seize alcohol from young people who are under 18 years of age, who are clearly obtaining alcohol illegally.
"It is disappointing that while many within our local hospitality sector continue to make significant sacrifices, either remaining closed or operating professionally within the current health regulations, others seem to think they are exempt from the restrictions and licensing legislation.
"If you have any information about the illegal sale of alcohol, contact us directly on 101, or submit a report online using our non-emergency reporting form via http://ow.ly/PYql50E2njb.
