A similar thing happened to my daughter a couple of weeks ago, no-one did a thing... disgusted I rang the bus company and complained, they said there was not much they could do as it needed to be reported there and then.
Ok I said, well then take it on spec that tomorrow I will be with my daughter and if this fellow is on the bus I will take matters into my own hands, I have only one child, I am divorced and single with few responsibilities and will defend her with extreme prejudice so be warned there may be trouble.
Needless to say the police were on the phone a few hours later advising me to calm down..... my reply was to go tell the bus company to deal with there own **** first...... idiot wasn't on the bus and hasn't been seen since.
