Police forces across England have increased patrols to deal with potential COVID-19 violations and criminal behaviour on the first weekend pubs have opened since the third lockdown.
Extra officers have been deployed as authorities try to ensure social distancing rules are followed after restrictions were eased on Monday when pub gardens and restaurants were allowed to open.
As a result, thousands of people were out on the streets on Friday, with images from Soho in London showing scuffles between revellers and officers.
It was the first weekend pubs had been open across England since October.

The Metropolitan Police's Deputy Assistant Commissioner Jane Connors is eager to avoid any more trouble this weekend.
She said: ‘The Met is ready to welcome back people to the streets of London.
‘We will be stepping up our patrols to busy high footfall areas, to look out for everyone’s safety and to disrupt any criminal activity.
‘Of course, where we need to take action against those who dangerously flout the rules we will do. While the case rate has declined in London, we have seen the concerning position in northern Europe.
‘It is important that we all stick to the rules so further lockdowns, or restrictions, are avoided.’
Both the 10pm curfew rule and the requirement to order a substantial meal with a drink have been scrapped, but social distancing must be abided by.
PC Connors said he was confident most business owners would act responsibly but added they would “engage, explain the regulations and if needed take action.”
Primrose Hill, in north-west London, will be temporarily closed at 10pm each night to prevent any gatherings and parties being held there.
West Mercia Police and Humberside Police also confirmed they would be increasing patrols to deal with the extra number of people expected on the streets.
Due to Prince Philip’s funeral, the Met has had a protective security operation in place in the vicinity of Westminster and Buckingham Palace throughout the week to keep people safe and to deter criminal activity.
This highly visible policing operation will continue through the weekend, the Met confirmed.
PC Connors added: “While restrictions have recently eased, we need only look at what is happening now in some parts of Europe and our own recent experience to see how quickly things can change.
“We are still in the midst of a global pandemic and we must all continue to do what we can to prevent the spread of the virus.”
The next date earmarked on the road map is 17 May, when socialising indoors will be permitted under the “rule of six” if the prime minister judges that the vaccination programme is safely breaking the link between infections and deaths.
