Depends who you classify as getting caught by, but my one and only time the old bill were involved. It was a long time ago (got to be at least 15 years ago maybe more), way before the internet had revolutionised the industry. It was all classifieds in local papers and telephone box cards. It was a Saturday morning and I had called some card from a box by the old Marylebone Library (i'm sure there are plenty on here who remember Knox Street and the shoes on the window sills on the Gloucester Place basements.)
The Apartment was on the first floor of a new build up the road, on the corner of Harcourt St & Old Marylebone Lane to be precise, it looked good. Went in saw the maid who in the old days you used to tip a quid or two for opening the door and showing the girl in.
Anyway to cut a long story short, about two minutes after I had shot my load there was some really loud banging on the apartments door. I thought at first that it was a pimp, the maid came in put her fingers over lips as if to say be quiet and whispered 'don't worry all ok, they go soon' more banging and then I distinctly heard the word 'Police' at which point the maid left the room.
I started to get a tingling in my balls (nope not the type that means round two!) The WG looked at me and said it will be ok, wait in the bathroom/toilet, I had my jeans on and tshirt on, back then I used to wear biker style boots so I picked them up and said sod that, I walked over to the sliding windows and said I'm going out here, I think she thought i was going to wait out there, which I was at first, but then I looked, didn't see any police vans or cars and thought 'fuck it, its only about a 10 foot drop onto the pavement, I can make that.' So over the ledge I went. Landed, stuck a fag in my mouth and walked away thinking I was joe cool, I turned the corner and saw the police car. The feeling of being Joe Cool disappeared instantly, balls started tingling again, and didn't stop until I was in McDonalds on Baker St. Not sure what they could have done, whether i would have been arrested or if they were just on the take, but all I knew was I didn't want them or anyone to nick me in a brothel!
