Hi there, As name suggests, Im a foreign visitor; have been here for almost 2 months and will leave in approx. 3 months time. 22 days ago, I was issued with a PFN by LU. I have a monthly Z1 - Z3 ticket on my oyster. I went to visit a friend and exited at a z4 station with no gate/barrier (entered at z2) Ignorance proved pretty bliss at the time and I strolled towards the station exit and failed to tap out. I was called over by a plain clothes tfl officer who identified himself and asked why I didn't tap out. I simply explained that I saw no gate and mindlessly kept walking and apologised for the action. He explained to me that this was a crime and that I could be prosecuted for fare evasion, then asked for my ID. I advised that I only had a foreign drivers license as I was a tourist and that I didn't realise not tapping out was a criminal offense. When he realised that I was foreign he appeared to change his mind and explained that instead he will issue me with a PFN. I didnt have £40 on me to pay it then and there, so he asked for my address, albeit it a temporary one, called some one to verify it (god knows who, since im not registered to any address here?) and told me that if I don't pay the penalty fare, it will be taken over by debt collectors, bad credit will be marked against my name in the UK and that I may be stopped upon leaving or trying to re-enter the country. I completely understand and acknowledge that I failed to tap out - and of course now know that this is a (serious) crime in the UK. I'm hoping to get some advice or clarity around the following questions please, if possible.. 1. I know that I am probably really pushing my luck here and standing myself in front of a firing range, especially as I am somewhat in the wrong, but (here goes...) as a foreigner, how likely is it that I can just close my eyes and pretend that none of this happened (especially as the 21days has elapsed - lost the ticket.. found the ticket!) and leave in a few months without any consequence? I am slightly concerned about the enter/exit UK thing? Though also suspicious of his truthfulness. I have read many things about PFN's initially being a civil matter, but that they can be withdrawn and TOC can choose to prosecute, resulting in a criminal matter for intent not to pay the PF. 2. If advised to pay, would it still be possible to pay the £40 by postal credit card, as I have not received any other 'reminder' type correspondence? 3. Should I just pay the £80 as it's past the 21 day mark and count my blessing I was invited to a court date as he mentioned? Thanks for the help in advance. Much appreciated! It might be worth mentioned that I have done some casual work while here, so am registered with HMRC.
