Right the full story as relayed again tonight by mate!
He had only started working on Fridays having been on short weeks until then. Uses Virgin trains to/from Manchester so he can get cheaper Virgin only trains. However, going in during the peak you can't get the cheapest options which is peak single in and cheaper single back so he buys single in the morning and single at Man P to come back.
On this Friday there had been a couple of 'early doors' beers and when he got to the station there were the usual Friday queues that he wasn't expecting so he just jumped on the train. When tickets were checked he said he didn't have one and the guy said that machine was at other end of train so to pay on arrival in Macclesfield. This is where he went wrong, for whatever reason, and he just left the station.
As he went out of the doors after the ticket windows onto the road he was stopped by some inspectors who took his details 'for a caution' and said he would receive something through the post.
When the attached letter arrived he wondered if it was dodgy due to the content which is what I was asking about rather than whether he was in the wrong.
BTW - genuine friend, wish I could be whisked into Masnchester by Pendo each day rather than driving halfway across Cheshire! Must be one of the fastest commutes in the North.
Unfortunately your friend has acted in precisely the manner that a Court will accept as a valid basis for Prosecution.
He has no grounds for defence because he was told to pay at Macclesfield and failed to do so.
At this stage the matter appears NOT to have been progressed as he has not received a summons.
His best course of action at this stage is to respond immediately to the letter, which does not request any sort of information that cannot be established from a phone directory or the voters register.
I would have expected the letter to make reference to SET however do not rely on that to form a means of avoiding Prosecution, as the Courts will not allow a simple technical error to be used as grounds for setting aside a case - as many motorists will attest !
It may well be that your friend may be given the opportunity to pay, even at this stage. It depends upon what he said when interviewed under caution, and how he explained his failure to pay. Obviously the Train Manager called ahead and thus he was expected at Macclesfield.
I am very surprised to read that the Train Manager did not have his machine with him. From my experiences on travelling Virgin, I have never known a TM do a ticket check without one.
