Meanwhile, Sussex Police have arrested two men and appealed for witnesses after another man suffered serious injuries in a fight involving around 20 people.
Officers were called to Montpelier Place, Brighton, at 10.15pm to find the victim, who was taken to Royal Sussex County Hospital for treatment, where he remains in a serious condition.
There was an increased police presence in the area while inquiries continued, with detective inspector Owen Radley urging “anyone who witnessed the assault to make contact with us immediately”.
Superintendent Mike Walker, gold commander for North Yorkshire Police’s response to Covid-19, said the force would undertake extra patrols to ensure public compliance with the regulations.
Meanwhile, chief constables in the north-west of the country said they would target the minority of the public who flouted rules by holding large gatherings, music events and parties.
And on social media Londoners reported high levels of traffic in the city as people attempted to leave before lockdown.
“Total traffic madness cycling home at 7pm,” Mary Creagh, chief executive at walking charity Living Streets tweeted.
“Tonight, everywhere is a high traffic neighbourhood.”
