I reported my neighbour to the police today and now I'm scared →[More:]I've had some concerns about the guy who lives upstairs from me for a couple of years. He has a vile temper and I've heard him screaming at people on the phone. Probably five times in the last two years, women have left his flat in a hurry, after I've heard yelling/screaming, sometimes in the early hours of the morning.

The women are prostitutes, and I say this with some certainty. He is 60-ish, the women I've seen leaving his flat in daylight are all late teens or early 20s, and wearing short skirts, high heels, skimpy tops (even in winter).

Yesterday evening there were police at his flat for some time. (I saw them leave. They were not 'uniform' coppers, but wore navy blue sweaters with 'Police' on the back.)

Later he went out and returned just as I was going to bed, probably around 2am (our clocks went forward last night). He was not alone.

This morning I'd just got up and I heard what sounded like a scuffle, something being knocked over, raised voices. A short while after that a taxi drew up (from a local company), and a young woman, who was crying, walked over to it. A few minutes later she was back at his door and the cab had gone.

Because his flat is the top floor, he has an intercom, and she was talking to him through that, trying to get him to let her in. I could hear her from my bathroom, she was saying "you promised to take me home, the cab was £35, I don't have any money".

Then I heard her say "If you don't let me in, I'll tell the police about ..." (didn't hear the rest). He must have said "how do you know about that?" because then she said "because I heard the recorded message when you came in". I think he must have threatened her because she began crying and begging "please, please, Vic, don't, I won't tell, I promise".

Anyway, I had to go out and as I did, I asked her if she was ok. "Not really" she said. Then she asked me how to get to Kilburn (which is a hell of a way from here, although it's do-able on the Tube). I said if she wanted I'd give her a lift to the station, but she said she didn't have any money for a ticket. I told her not to worry about that.

So, we got in the car and as we drove away she began crying again, I think with relief that she was away from him.

She told me that he'd pulled over in his car in Kilburn and picked her up last night. Obviously she was a working girl, although neither of us mentioned that. She said that she'd gone back to his flat, he'd made her a drink and the next thing she knew she'd come to and found herself tied to a chair. She was terrified, and the noise I'd heard was her smashing the chair to free herself. He'd promised to take her home, but obviously decided not to.

She said he is very, very weird and she thought she'd had a lucky escape.

I took her to the station, showed her which trains to get (she's from Leeds and not familiar with the Underground) and gave her a fiver for her ticket. The last thing she said as she went off to get her train was "if you hear anything else like that again, promise me you'll call the police".

I am so concerned about this that I drove to the local station and spoke to a woman officer. She took the details and someone will call me. I said that I'm worried about this being traced back to me, but she put a 'do not divulge' next to my name and phone number. If there is a follow-up to this, then he will not know if it is me or her who's reported it.

Jeez, I knew he was a creep but, fuck, he's a total sicko. I just hope there isn't any comeback to me from this. He must have known I know about what happened because he would have seen her get in my car. Maybe I shouldn't have said anything, but next time it could be worse, he could really hurt someone.
