A Whittlesey pub was forced to shut for 48 hours over police fears that a party inside the premises could lead to disorder or potential nuisance.
Customers could not enter the Railway Inn after a police closure order ran from 1.15pm last Saturday until 1pm on Monday.
The decision was taken after Cambridgeshire police were made aware that upwards of 300 invites had been sent out via social media for the party.
A dispersal order was also issued which prevented anyone from being in the immediate area of the pub in Station Road.
Last month Fenland District Council’s licensing committee effectively banned the pub from selling any alcohol until the current landlady leaves.
This followed supplied evidence of several assaults - ranging from common assault to grievous bodily harm - threats made to members of the public walking past the pub, and complaints about noise, crime and disorder.
The closure notice was the first one ever handed out in Whittlesey.
PC Phil Richardson, licensing officer, said: Cambridgeshire Constabulary takes all antisocial behaviour seriously, as evidenced by the actions taken at the Railway Inn.
“Local residents have been inconvenienced by the pub, as have members of the public and victims of crime at the premises.
“It is hoped that actions taken by the licensing committee and the owner of the premises, Star Pubs & Bars, will resolve the issues to the satisfaction of the community.
“All issues of antisocial behaviour are monitored, and all those coming from, or connected, to a licensed premise, will also be reviewed by one of the constabulary’s licensing officers.”
The pub’s closure order was only meant to last for 24 hours until the matter was re-evaluated and an extension agreed.
PC Richardson added: “The pub complied with the order and no arrests were made.”
Louise Barnett, spokeswoman for Star Pubs & Bars, said: “We are aware of a number of allegations regarding this pub.
“We have engaged closely with the police to address all of the concerns raised and continue to do so to ensure a successful outcome for all parties.”
