For a few minutes I kept hearing this kind of muffled noise that kind of sounded like someone in the garage or next door using an electric drill for a few seconds at a time, every 10 or 20 seconds.
I was in Bowthorpe ward then mile cross ward in the morning, we were in chapelfields between 1 and 2 then we were in town close ward, but we walked from chapelfields to there and back again.
