Last week I boarded an SWR service from station A which was manned and had barriers. I was intending to purchase an eticket towards station d but mistakenly bought for station B as I was in a rush and couldn’t see well due to not having glasses. I also had the 16 -25 railcard option automatically selected but it was a week out of date and I didn’t realise. While on the train I saw my ticket had the wrong destination and I attempted to change it but couldn’t due to Network disruptions as my network provider is making improvements in my local area. When reached station D, i had forgotten about not having a ticket and I tried to quickly buy one but I bought a ticket from station c to d which was the previous stop. I was stopped by an rpi or an rpa just before the station exit and I was asked to produce my ticket. Whilst checking he asked for my railcard and I told him I have forgotten it. He then asked for my name and I gave it to him and he also asked for id and I said I don’t have any and he saw my bank card in my wallet and asked for it. I thought I was going to pay the excess fare and he didn’t make clear what he was doing and I gave it to him. He started to note down account number and sort code to which I was confused and surprised by. He then said he can check if I had a railcard and at that moment I realised it was out of date and I replied with I can pay the excess and there's no problem since I was late for work. He then said asked for my address and said if I give him the wrong one I can be prosecuted at that point I realised I was being under the suspicion of committing an offence because of his stern tone. I then gave my correct address to which he checked out on the phone to an office and the address was correct He then asked why I lived far from station c if I got on there as I told him that I came from station c when he asked me as I didn't want to get in trouble. He then said he can check cctv at station c to see if I was there. He then called to check my account number and sort code on the phone and he saw I had an e ticket from station a to b. and I then told him I came from station a. He then said that I will be prosecuted or he will refer me to the prosecutions department, I can't remember which. I was never informed that I had a right to silence and he only had a right to ask for my name and address. I basically self incriminated myself and I didn't know that I was free to leave at any time. He didn't give me a caution or an mg11 or a TIR. Can this information that I gave be used to prosecute me under RoRA?
