Six people were arrested as police broke up 405 house parties across Scotland at the weekend in alleged breaches of coronavirus regulations.
Just one fixed penalty noticed was issued following the incidents between Friday and Sunday with police giving advice while dispersing party-goers.
Two officers were allegedly assaulted at one such incident in Muirhouse, Edinburgh, with the windows of two police cars also smashed at around 5.35am on Sunday.
After the incident two men aged 47 were arrested and expected to appear at Edinburgh Sheriff Court on Monday.
Elsewhere, a 21-year-old man was arrested and charged for allegedly obstructing officers as they responded to another reported house party at a tower block in Muirhouse, Motherwell, at around 11.30pm on Friday.
Deputy Chief Constable Malcolm Graham said: “The figures from this weekend show that we will use the powers we have to disperse parties which breach the regulations and will enforce where necessary.
“We will not tolerate blatant disregard for the legislation which is there to help stop the spread of the virus.
“I’m extremely disappointed to learn that two officers were allegedly assaulted while responding to a party in Edinburgh.
“Our officers find themselves dealing with situations on a daily basis to protect the people and communities we serve, and are trained to a high level to deal with violent and confrontational situations.
“However, being assaulted is not simply part of the job and it cannot be tolerated.
“The Chief Constable made it clear that assaults against officers and staff is utterly unacceptable in his public pledge made to tackle this last month.”
It comes as the Scottish Government altered guidance limiting the number who can gather indoors or outdoors to a maximum of six people from two households.
And stricter lockdown restrictions around Greater Glasgow will continue until the next review date of Tuesday September 22 in Glasgow city, East Renfrewshire, Renfrewshire, West Dunbartonshire, East Dunbartonshire and North and South Lanarkshire.
Mr Graham added: “Our approach throughout the pandemic has been to engage with the public, explain the legislation and guidance, and encourage compliance, only using enforcement as a last resort.
“We will continue with that approach, but we will not hesitate to use enforcement action where it is necessary.
“We have had almost 68,000 interactions with the public since the start of this emergency and have had to take enforcement action on only around 3,600 occasions.
“However, we will not tolerate blatant disregard for the law, which is in place to help stop the spread of the virus, and we have been using our powers to disperse large groups of people at house parties.
“The Chief Constable has made it clear that we are asking people to take personal responsibility to do the right thing and remember the purpose of these measures is to aid the collective effort to stay safe, protect others and save lives by preventing the virus from spreading.”
