Yes, several incidents in my 20s/early 30s.
I was coming out of the tube and passed him going the other way at the top of the escalator. He was quite distinctive looking. Walked home. I lived in a mansion block. entrance up some stairs. I was putting my key in the lock when he came up behind me. Asked me the directions to a road. I said I didn't know (I didn't). He then got angry with "why are you being a stuck top bitch" type comments. Started to come up the steps. I turned the key and he pushed his way in behind me. Pinned me up against a wall inside. Assault. I pushed him off, managed to get up the stairs to my flat. Called the police, they came and told me he probably just danced me, I should be nicer and wear longer skirts (I had an ankle length coat over my "provocative" knee length skirt, but ho hum). Tried to make a statement, the female officer wasn't interested. I lived in a nice area, and that sort of thing didn't happen around here. A few nights later, he was waiting outside my mansion block, I managed to get passed him and inside. I moved to the other side of London after that.
2 years later, I was contacted by the police. An off duty police woman had been assaulted and a man arrested. Her account of his M.O. matched mine and that of another woman, whose account had been dismissed the same as mine. A police colleague had trawled through previous reports and linked the 3 of us. Victim 2 could have been my twin sister. The 3 of us picked him out of a line up. It went to court. I was a far too dispassionate witness, needed to show a bit more emotion (but not as much as the police woman victim, who went to pieces on the stand). When doing such humiliating things as showing the judge and jury how far my skirt came down my thighs, I didn't show the appropriate emotion.
Turned out, he lived on my road (one of those very long London roads that can be beautiful and wealthy at one end and a scary shit hole at the other). Also turned out that the police completely fucked up the evidence (including CCTV footage of him doing a 180 to follow me out of the tube), and a load of evidence had to be ignored. He was found not guilty. Found out afterwards that t the time he assaulted me, he had recently been released from prison for rape.
I once had another man follow me from the tube, talking at me for a good half mile. He only fucked off when I got to the restaurant where I was meeting a friend. He claimed we were good friends at university. He couldn't remember which university that was, what my name was or what either of us had studied. I honestly cannot fathom what goes through the heads of men like this. Is this some sort of seduction tactic that works for them?
Not exactly followed; but, when I was heavily pregnant and standing on the tube, some random got off his seat and came right up to me, his face right into mine, and started screaming incoherent nonsense. The rest of the passengers just sat there. No doubt, if I had bothered to report it, it would have been dismissed as some poor disturbed fellow I should feel sorry for.
I am glad that I am now old and invisible.
