I’ve now edited and uploaded a 12-minute-long video record of the night’s events. Click the image to view it on YouTube.
Having now edited the footage and listened to the soundtrack closely, I’m convinced that the noises had separate causes. I’ve amplified on the video soundtrack the ‘door handle’ and the ‘riffling noise’ from the cell next door, and it’s apparent that they are quite different sounds.
I should also point out that (as far as I knew) I was alone in the town hall apart from the security guard, who remained in his station in another part of the building, upstairs.
