Three students have been fined £10,000 each for flouting coronavirus restrictions, and hosting a party.
The party took place on Saturday until the early hours of Sunday morning hosted "up to 100 people," reports Metro.
Police were called to a house in Bowthorpe Road in Norwich hosting the event, despite a ban on holding gatherings of more than 30 people in the region.
Of those who were fined, two women were aged 20 and one 19-year-old.
All those involved are reportedly University of East Anglia students.
A spokesperson for Norfolk Constabulary added: "We all have a role to play in keeping our county safe and yesterday’s gathering was a blatant breach of the Health Protection Regulations.
"We will all have a role to play in keeping our county safe going forward and we won’t hesitate to take action if needed as yesterday demonstrated."
The women "were issued with the fixed penalty notice for contravening the ban on being involved in holding a gathering of more than 30 people."
In a statement released by the force it also warned of the rising infection rate around the country.
They said: "As a police force, we fully appreciate how difficult the past six months have been for the county and we are pleased that the vast of majority of people have played and continue to play their part, following the guidance and legislation helping to protect Norfolk and prevent the spread of Covid-19.
"Our focus will remain on our use of the 4Es – engaging, explaining, encouraging and then enforcing when required."
Last month six students living in a shared house near Nottingham University faced a hefty bill after a weekend party “got out of hand.”
Fifty people were at the boozy bash in Lenton, Nottingham, when the limit on group gatherings is currently 30.
Council community protection officers attended the property at around 7pm on Friday after a complaint that the party was breaching lockdown rules, but the 19-year-old man hosting the party reportedly became “hostile” prompting officials to get the police involved.
The teenager has since been landed with a £10,000 fine.
