Up to 200 people turned up to an 'unlicensed music event' during lockdown.
Thames Valley Police has handed a £10,000 fine to a 23-year-old man from Hackney, suspected of organising the event on December 31st.
Officers say around 150 to 200 people had gathered in breach of Coronavirus laws on New Years’ Eve, on Bicester Road in Kidlington.
They took action to disperse those who had gathered 'for the safety of the public and officers and to minimise the potential for disorder.'
Silver Commander for Thames Valley Police’s response to Coronavirus, Supt Bruce Riddell, said: “This event increased the risk of transmission of Coronavirus and also caused disruption to the community.
“The vast majority of people within our communities have and continue to do all they can to stop the spread of Coronavirus and for this we would like to thank them.
“Overall cases seem to be falling but regulations remain in place which are there to protect us all, particularly around large gatherings.
“Throughout the Thames Valley our officers will continue to engage, explain and encourage people to follow the Coronavirus legislation, however where they see people wilfully and blatantly ignoring the regulations, particularly by gathering in large numbers, we will look to issue FPNs or use other enforcement such as dispersal or arrest.
“This incident caused concern in the community at the time and the action taken should serve as a reminder that people who are suspected of being involved in the organisation of such illegal gatherings will be issued with an FPN.”
Following an investigation by the Kidlington Neighbourhood Policing Team, a 23-year-old man has been issued with a £10,000 fixed penalty notice.
