The Deptford Mounties

Returning from work via Deptford station last Wednesday evening I was startled by the unexpected sound of hooves on tarmac. Took a glance behind me and sure enough there were two mounted police slowly proceeding down the High Street... eventually taking up position outside the Deptford Arms, on Reginald Road. Seemed a bit odd really and I don't recall any mounted police in the area before. Granted it was the night of the Champions League final but surely the two events weren't connected - I'm pretty sure there aren't that many Man U, and even fewer Barca fans, in SE8! Or perhaps they were just following up that notorious Daily Mail slight on Deptford...
