In the video the cyclist can be seen approaching a set of traffic lights which changed from amber to red. The cyclist had enough time to stop within the bike box at the junction but was knocked to the ground just as he stopped.
From the rear facing camera we can see just how close the bus was travelling behind him and it looks as though he expected the cyclist to run the red light with and was ready to run the red also.
The bus involved in the incident belong to Go Ahead London and was operating on the 355 route from Brixton via Clapham Park, Balham, Tooting to Mitcham which is a total of seven miles.
Attention all ye 'cash for crash', 'where's the red light', etc. No cyclist has EVER thrown themselves under a bus for profit. Sheesh. pic.twitter.com/tzpERastw6
