Last night at 7pm, as I was cycling north on London Road, I stopped at the red lights by Garden Row. Across the road, by South Bank university, I witnessed a guy brandishing and swivelling his rather large and flacid "instrument" at a lady shouting "you want it, you want it"... She shouted back at him and left in a hurry and as the guy was about to cross the road, I quickly rode away (I was so distracted by the scene that green light was on for a while). Quite scary as it is rather dark at that spot. So be careful ladies.
Not sure if that should be reported, I did not get a good look at him as it was too dark but he was tall, black, middle age.
