Police are investigating after a house party was attended by more than 300 people.
Officers received reports of a large-scale gathering run as a commercial event at around 12.20am on Sunday, August 30.
The organisers of the party in Midlothian could now face culpable and reckless conduct charges as a result.
Police say the paid-for event was in clear breach of the current legislation in place to prevent the spread of coronavirus.
All those present were dispersed by officers and a 29-year-old man was issued with a fixed penalty notice.
Further inquiries are being carried out to investigate potential culpable and reckless conduct charges and licensing breaches.
Deputy chief constable Malcolm Graham said “Those attending this organised event showed a blatant disregard for the regulations in place to help save lives and prevent the spread of coronavirus.
“Further investigations are being carried out with a view to what other charges may be brought, including culpable and reckless conduct.
“Anyone attempting to hold such an event, or any party in clear breach of the law, should be aware they will be met with a robust response from Police Scotland.
“I cannot stress enough the serious risk to public health an event of this size poses not only to those present and anyone they come into contact with, but also the wider community and all those from the emergency services who attended.”
Councillor Stephen Curran, chairman of Midlothian police, fire and rescue board, said: “Those 300 or so people didn’t just put themselves at risk of contracting coronavirus, they put residents across Midlothian and beyond at risk.
“To call them selfish and irresponsible is an understatement. We realise it can be challenging following the guidance but if the majority of us can do it then so can they.
“We are working hard to avoid lockdowns like those happening in and around Glasgow but we need everyone to help keep Midlothian safe. So, please follow the guidance. It will save lives.”
During last weekend, police officers responded to reports of around 300 house parties across the country, dispersed those attending and issued six fixed penalty notices.
