Spp that pass in the night

Who could live in a garden like this? A tiny lawned space facing the road, right in the city centre near Iron Bridge, though there is a large old garden hedge. In that hedge has been a growingly prominent small gap and suggestion of a track, leading to next door; and in that lawn some odd scrapes and holes.

The neighbouring flat's trail camera revealed all.

I've seen badgers twice before either in the front garden or nearby grassed areas, and many times near the University campus. Even with a large home range (for which the average is reported to be 50 hectares, up to 300ha in low quality foraging habitat), one wonders where the nearest sett might be. There aren't too many obvious places within 500m, a typical roaming distance.
