I also noticed it cycling past last night. It sent shivers down my spine. Could be a student staying at the Hall of Residence across the road?
Lots of pedestrians seem to take a risk and cross the road at that junction and around St George's Circus roundabout. Very sad.
I, too, noticed this on Monday. Last week or the week before my daughter said she went to get a bus at the St George's Circus stop on the Waterloo Road just past the H10 and it looked like a 172 bus had just squashed someone on or near the Circus. Waterloo Road was closed. I imagine that's what it was, sadly.
