Up to 200 people gathered for a party at a university student hall, flouting coronavirus restrictions.
Police said officers had attended halls at Coventry University in the early hours of Tuesday morning.
Officers have worked with the management of Arundel House to close some communal areas and increase security, West Midlands Police said.
The university is “deeply concerned” over a video of the party and condemned the “blatant breaches” of rules.
Footage from accommodation on Whitefriars Lane emerged on social media showing a large group of people who were apparently not adhering to social distancing rules.
Current government guidance states that only groups of six people or fewer are allowed to meet and students have been told they must limit socialising, staying within separate “households” and being taught in managed groups.
Coventry University said it “strongly condemns the blatant breaches of the rule of six and other guidelines as they risk the health of our students, colleagues and the communities in which we are located”.
Ian Dunn, the university’s Provost, described the footage as “outrageous and deeply unfair”.
He told the BBC the university was taking the incident “very seriously” and he was confident its code of conduct had been breached.
However “the vast majority of our students are behaving so responsibly,” he added.
A spokesperson said the university’s code of conduct had been shared “widely” with students, making clear a failure to follow the health guidelines would constitute a breach of the university’s disciplinary regulations.
“Appropriate action” will be taken if any involved in the video are found to be students, they added.
Police said officers were examining CCTV of the gathering in Coventry and “will take action if evidence comes to light that this was a planned party”.
Nido, which runs the halls, said it had restricted visitors to the building and stepped up security following the gathering.
“We do not want the actions of a few to affect the experience of many,” a spokesperson said.
