Nearly 5,000 incidents of bus drivers being attacked have been revealed by Conservatives on the Greater London Assembly.
Figures uncovered by the City Hall Tory group's police and crime spokesman, Roger Evans, show 4,967 incidents were reported between 2010 and 2013.
Four in 10 (38 per cent) of these incidents involve bus drivers being either physically assaulted or threatened with a weapon.
Mr Evans said: “The number of bus drivers facing physical attack or verbal abuse on London’s bus network is alarming.
"Nobody should have to put up with threats or violence while doing their job. I fully appreciate that money has been invested in patrols on our buses by the police however we need to go further."
Mr Evans has called for a full review of policing across public transport in London and "well-publicised sting operations" to deter further abuses.
