Police in Staffordshire say they are aware of posters surfacing online advertising mass gatherings at various locations across the county.
Images have been shared on social media promoting events across the UK.
Chief Inspector Karen Stevenson, neighbourhood commander for Stoke South, said: “We are reviewing this information and the reports we have received from the public and we will be monitoring the situation closely to ensure we are able to respond to any unlawful activity and enforce the law fairly and appropriately.
“The government guidance is clear that gatherings of more than two people from different households are not allowed as this poses a significant risk of spreading Covid-19.
"Our local communities will also not want large gatherings when we are all trying to protect our loved ones during this pandemic that has killed tens of thousands of people.”
The message from police has been echoed by health bosses in the county.
Staffordshire and Stoke-on-Trent CCGs say they strongly urge people not to attend, as mass gatherings run the risk of spreading the virus, causing unnecessary deaths, and reversing all the progress made so far.
Dr Lorna Clarson a GP and Chair of Stoke-on-Trent CCG says, “As a GP I am really concerned about the plans for mass gatherings on social media.
“The numbers of infections in Stoke-on-Trent are still rising and we are seeing more admissions to hospital with Coronavirus than we have before, this is not the time to ignore the advice to stay at home as much as possible.
“I would urge the people of Stoke-on-Trent and surrounding areas not to participate in these gatherings and to stay at home and enjoy any good weather with your household at home.”
