Hi, can someone please help me.
. . . . his report would be sent off and they would call my work (I had to give my work and HR details) to verify how many days I work (I am part time) and check my bank account to verify I use contact less payment to travel from Liverpool St to west end london. Is this possible?
I'm stuggling to understand exactly what help you are looking for, but I'm happy to guess, in case that will help.
It seems clear from your explanation that the Inspector had reasonable evidence to justify further enquiries which might help in determining whether or not you were a regular fare evader. Whether you were evading the fare or not is not the point in understanding this fact. It is whether your explanations and the tickets you presented to them gave them reasonable grounds to suspect that you were evadng the fare. I'm going to guess that you will be able to agree with me this far.
When making these enquiries, their main objective is to provide evidence which either, confirms your fully lawful and paid-for travel, or, which confirms your unlawful and unpaid travel. Again, I hope you can agree with this.
It then seems (though this is very unclear from your posts) that you made a statement about your work pattern which must have appeared to be relevant to you when you were justifying your patterns of behaviour (travel and ticket buying). If you did try to claim that this was relevant, then it seems reasonable to me that any investigating officer would want to be able to corroborate that statement with evidence from that third party. Perhaps you now wish that they didn't - you could have asked them not to, or you could have declined to identify your employer.
Furthermore, it is often helpful when trying to establish the facts of a matter, which will include the identity of the person being questioned who will shortly be leaving perhaps never to be seen again, to ask them for details which will assist in identifying them. Perhaps details of an employer, of a place of education or some other external route to assist in confirming their identity will all help.
Finally, in the unfortunate event that the evidence does point to fare evasion, and that it then proceeds to a prosecution, and then that the prosecution succeeds, and that an "attachment of earnings order" is made, then the employer's details WILL have to be provided. So it makes sense to request those details at the point of the initial interview. [But we should all accept, that with the painfully slow pace of prosecutions through the Courts, then it has to be a realistic consideration that a suspect will have changed jobs before it gets anywhere near a Court. The way thing are right now, there's an equal prospect that the Court will have ben closed down!).
Of course you are under no obligation to provide the name of your employer, but it will often help both parties to do so. On the other hand, if the person being interviewed really is a regular fare evader, then I can see very clearly why they would NOT want to give any information like that to the investigating officer. But, inevitably, their refusal is only going to contribute to the investigator's doubts.
Does this help to answer your question?
