Prisoners in jails across England have been using smuggled mobile phones to broadcast drug use and partying on social media.
Inmates, who are not allowed smartphones, have used the handsets to post footage from jails in London and Birmingham, as well as one near Wolverhampton, in the last month.
The video shows bundles of cannabis wrapped in paper and clingfilm spread out on the floor, and many more closed paper wraps inside what appears to be plastic packaging for a loaf of bread.
All the videos were anonymously published to Snapchat, which allows anyone to find public videos by location without revealing the user.
Such contraband is often thrown over prison walls “on a daily basis” and sometimes flown in by drone “like a pizza delivery”, according to Glyn Travis, the assistant general secretary of prison staff union POA .
“Prisons are currently awash with drugs and mobile phones,” he added.
Footage from inside the Winson Green jail in Birmingham posted earlier this month shows inmates dancing to loud music in a cell and relaxing on the prison gantry.
An inmate at HMP Oakwood, which is near Wolverhampton, has also posted videos showing life in the jail.
The Ministry of Justice has branded the behaviour “completely unacceptable”, adding that “those who break prison rules will face tough punishments, including extra time behind bars”.
