A major police operation has been launched after violence flared in Niddrie Around the same time in Glasgow, a man outside the OVO Hydro threw a flare into a crowd of people. He was arrested by security personnel at the scene. Two people were arrested for the matter. Assistant Chief Constable Tim Mairs, Gold Commander for Operation Moonbeam, said: “In some areas, particularly in Edinburgh, individuals have shown a blatant disregard for public safety and the emergency services and have actively targeted police and firefighters during duration of duties. “This behavior is completely unacceptable and will not be tolerated. I want to make it absolutely clear that significant further investigation will be conducted in relation to all of these incidents. Don’t think that just because you evaded the police at night, we won’t be knocking on your door in the near future.” He added: “Everyone on duty during the Night of the Fire showed exceptional professionalism and dedication to keeping communities safe from harm in extremely difficult and challenging conditions. I am grateful for all their efforts.” Firefighters attended 242 incidents in the western service area, 89 in the east and 25 in the north between 3.30pm and 11.30pm on Saturday. As it became known, no injuries were reported by the firefighters. Assistant Chief David Farris, service director for the SFRS, said: “We are disappointed to report five assaults on our firefighters. In the lead up to Bonfire Night, we had spoken about this type of unacceptable behavior from a small minority which sadly happens year after year. “Our staff should be able to carry out their role without being attacked and it is disappointing that people have tried to harm firefighters and have damaged our appliances and equipment.”
