Police were called to break up an illegal gathering in a tunnel in Glasgow's west end.
Cops were called to Kelvindale Road on the early hours of Sunday morning after reports of a 'party'.
Four people were fined for breaching coronavirus regulations while the rest of the group was dispersed, the Daily Record reports.
A 20-year-old man was also charged with culpable and reckless conduct.
The abandoned Kelvindale tunnel, which is around 200 yards long, was only in use for 24 years, between 1896 and 1920 and used as a part of the Caledonian Railway’s Temple branch line.
Locals in the Kelvindale area told the Record there was around 20-30 youths in attendance at the gathering.
One source said: "I woke up as there was loads of noise in the carpark right outside my window, must have been easily 20-30 teenagers all drunk."
Another said: "It was bedlam. Easily a dozen police cars, dog unit and the fire brigade."
A Police Scotland spokesperson told the Record: "We received a report of a large gathering in a tunnel in Kelvindale Road in Glasgow at around 3.20am on Sunday, 21 February.
"Officers attended and four people received fixed penalty notices for breaching coronavirus regulations and one man, aged 20, was charged with culpable and reckless conduct.
"The rest of the group dispersed."
