‘Disgusting’ Bonfire Night violence against police
Assistant Chief Constable Tim Mairs said: “The overwhelming majority of Scotland enjoyed Bonfire Night safely and responsibly, but once again, a minority of individuals have been responsible for an unacceptable and frankly, disgusting level of disorder that left communities alarmed and police officers injured.
“We took learning from last year’s operation and enhanced the level of public order resources available to local policing divisions to ensure we could get these assets into locations they were needed quicker, providing a more robust response to criminal incidents.
“The lower levels of disorder experienced in other parts of the country demonstrates that this approach was the correct one.
“Investigations into the offences that arose throughout Scotland on Sunday evening are continuing and we will make every effort to ensure anyone who was involved is identified and brought to justice.
“Police Scotland officers were subjected to unprecedented levels of violence, and yet they continued to demonstrate professionalism and dedication to keeping communities safe.
“I am both proud of, and grateful to, all of those who were on duty and put themselves in harm’s way to protect the public during this very challenging time.”
Fire crews tackle hundreds of bonfires
There were nine attacks on fire crews in Scotland as the service received nearly 900 calls to tackle more than 350 bonfires across the country.
Andy Watt, Assistant Chief Officer for the Scottish Fire and Rescue Service said: “This type of behaviour not only prevents our crews from bringing any emergency to a safe and swift conclusion, but it can impact on our emergency service colleagues – including the police – when they are supporting us on scene to ensure the safety of our personnel.
“We thank our emergency service partners Police Scotland for their continued assistance and we will continue to work in partnership with them to identify those responsible.
“This type of behaviour is, of course, carried out by a small minority within society and we once again thank our communities for their continuing support and working together with us to stay safe.”
