No the bus driver didn't do anything - TFL tell me they are told not to leave the cab except in an emergency, which whilst that makes me feel pretty unsafe, I do understand. I have witnessed a bus driver being beaten up on his bus and that was awful too. The police have been excellent, and whilst it is unlikely anything will come of the investigations I felt it was important to report it, and this is partly why I have posted on here so that others will do the same, if they come across this man. Also I would encourage you if you are a passenger on a bus and witness something like this, please ask the driver to call the police or call 101 yourself - no-one else on the bus assisted and as I was on crutches I couldn't get to the driver. Thanks :)
