An organised meeting of drivers in Wirral tonight led to a 48-hour dispersal zone being set up by police.
It follows around 80 cars, thought to be from outside the Merseyside area, gathering at The Croft retail park in Bromborough.
After the retail park was closed to them, the group then moved to other nearby locations.
The dispersal zone came into force at 7pm tonight (Sunday, December 27) and will run until 7pm on Tuesday, December 29.
It is thought some of those attending the gathering tonight will have travelled from areas which are under a higher Tier of Covid restrictions than those in place on Merseyside, which is in Tier 2.
The area covered by the dispersal zone includes the area bordered by and including New Chester Road and River Mersey, and from Dock Road South to Ferry Road, Eastham inclusive.
Chief Inspector Chris Ruane, said: “We’re keenly aware of the significant impact that anti-social behaviour can have on individuals and communities, and we will be targeting people we suspect of being involved in this type of behaviour in the area.
“The drivers of these vehicles, are believed to have come from areas outside of Merseyside (which may be in different Tiers and subject to additional restrictions) to meet up and we received a number of calls from local people who were concerned.
“Alongside the dispersal zone we will also use any legislation available to us in relation to Covid for those travelling into the area from outside the region.

“If people are making non essential journeys that are plainly in breach of current legislation we will take the necessary action.”
A dispersal zone gives police officers and PCSOs powers to direct people they suspect are causing or likely to cause crime, nuisance or anti-social behaviour to members of the public, to leave a designated area for up to 48 hours.
If they return to that area, they face arrest.
Anyone in the area with any information about this type of anti-social behaviour is asked to contact 101, or Crimestoppers anonymously on 0800 555 111. You can also follow @WirralPolice on Twitter and Facebook for updates and advice.
