Police are hunting a cyclist who headbutted a worker to the ground after a near-miss on a pedestrian crossing.
The cyclist ran a red light in Farringdon Street in the City of London at around 13:45 GMT on 22 August, narrowly avoiding hitting the pedestrian who was crossing the road.
He then got off his bike, came back towards the businessman and headbutted him in the face.
