British Transport Police and Westminster Community Wardens are
supporting TfL Revenue Protection Officers (jumpers to you and I) in
Lower Regent Street this morning.

They're getting on buses en-masse as they pause in traffic or at the
bus stops and ticketing evaders. I don't think that they're targetting
the 453 in particular, but it'd be interesting to see what their stats
are for OPO vs crew vs 453.
