Edinburgh locals were awoken by dozens of loud bangs during the night, with many believing they sounded like gun shots.
Residents in east of the city took to social media early on Wednesday morning, all equally puzzled at what was going on. The noise was thought to be fireworks being let off within Holyrood Park.
Starting around 3:30am and continuing for over an hour, one resident even left their flat to get some sort of explanation as to what all the commotion was about.
