Northamptonshire Police had a 'relatively peaceful night' after pubs and bars reopened for the first time in the county since March.
Lockdown restrictions were eased on Saturday, meaning pubs and restaurants could welcome back customers after an absence of more than three months.
A pub in the east of the county had to be closed down at 9.30pm as social distancing was being ignored and a beer festival was taking place in the back garden.
Police say the venue will be visited by licensing officers next week.
Officers also investigated a number of reports of potential illegal raves and music events, including one in Northampton's Brixworth Country Park where 300 people gathered to watch a live DJ.
The group left the site by 11.30pm, within an hour of officers arriving.
Extra police resources were rolled out across the county to deal with any incidents, but the streets were quieter than a standard Saturday night with some venues choosing not to open or to close early to avoid any risk of public disorder.
Officers have thanked the public for complying with the new Covid-19 social distancing regulations.
“I’d like to thank the many pubs, bars and restaurants which, in the overwhelming majority of cases complied with the regulations and ensured customers had an enjoyable, but safe night", ACC Simon Blatchly, Gold Commander for Op Talla, said.
“Northamptonshire Police had a well-planned operation for what we understood might be a potentially difficult evening, but footfall overall was low and some venues chose to either stay shut or close early to minimise the risk of any disorder.
“Some excellent proactive policing ensured we minimised the potential disruption caused by illegal music and car cruising events. This was an important first step and we’ll continue to monitor the situation closely, but I’d like to thank everyone for their co-operation as well as the many officers out and about keeping the public safe last night.”
