Yesterday my 18 year old son inadvertently purchased a child ticket from the ticket machine at Wokingham to travel to Reading. He didn't even realise he'd done it. He purchased a single as he was being picked up by me on this occasion, whereas he normally purchases a return, so was expecting the price to be less, so that didn't alert him. His ticket would not work in the barrier at Reading so he approached what he thought was a guard, but I think it must have been a revenue protection officer, who pointed out it was a child ticket and asked his age. He initially daid 15 - stupid I know- but told the truth when challenged and gave his correct name and address etc, showing ID. He was given the 'Anything you do say..' speech, then sent on his way. He said the officer gave him the impression he wasn't in too much trouble. I was concerned when he said about being cautioned, and started reading up about this, and of course have scared myself silly about the prospect of a criminal record etc. I do believe this was a genuine mistake as he was with a friend and probably not paining attention. He travels by train fairly regularly and has old tickets to prove he pays adult fare, and evidence on his bank statement that he purchased an adukt price return to Reading from the ticket machine less than a month ago. I appreciate no-one knows exactly wht will happen until we hear from the TOC, but am just seeking to put my mind at rest. Thank you
