A spokesman for Lane Ends pub in Bradford said the venue has implemented changes on Sunday following a visit by officers on Saturday.
A photograph of police outside the venue in the Five Lane Ends area was shared widely online, with claims that '200 people' were seen at the pub.
Today, in a statement posted on Facebook, a spokesman for the pub said that customers had been breaking social distancing rules and were also seen handing bottles out of the premises.

The pub confirmed that it has made changes to its social distancing policies in the beer garden as a result.
It said: "As many people have seen on social media, yesterday was quite eventful.
"Firstly thank you to everyone that was sitting down in the lounge, you made our job much easier on that side of the pub.
"The problems started mid afternoon when too many people wanted to get in the tap room and those that were in tap room were not abiding by the social distancing rules and refusing to listen to us.
"People were then buying our 4 bottles for £10 and passing them to their mates in the car park.
"Luckily the police came at 7pm and told us to close for safety reasons.
"So today we will be working differently.
"The beer garden will be closed.
"We have 100 seats available in the pub which will be allocated on a first come first seated basis.
"Once all the seats are taken we are sorry but we will have to refuse entry until a table becomes available.
"A queueing system at the top entrance will be used and you will be escorted to an available table. Also we will be operating table service only.
Again thank you to those that used common sense yesterday."
It comes after police confirmed they were called to the venue on Saturday following a safety report.
A spokesman for West Yorkshire Police said: "Police attended following a concern for saftey report that was not linked to overcrowding.
"A group was dispersed and the matter referred to licensing."
