The Edinburgh police have implemented a city-wide and divisional response to the upturn in theft of motorbikes and the subsequent anti-social behaviour that usually follows (noise, racing, riding without helmets, the wearing of masks/balaclavas and the filming of the behaviour for upload to social media sites)
The police are requesting assistance if you witness or become aware of this behaviour, especially, if you manage to catch any footage on CCTV. Equally, sightings and/or locations of potentially stolen bikes are of particular interest.
They have named their response to this upturn of anti-social behaviour: Operation Soteria
If you wish to report any such incident, report to the polic via 101 or email them at operationsoteria@scotland.police.uk
