This is not exactly your everyday situation, however, I have tried to find answers on other websites but failed. I found this site and hope somebody can help. I am a distant relation of those involved and have tried to keep things simple but this has got to stop as been going on for a while. For information, the eldest, who has confided in me, is extremely ill, physically and mentally (this unnecessary stress is obviously making them worse). The youngest (who is causing the problems) is married with children and works full time. It surrounds the fact that the younger brother has been sending threatening texts to an elder sibling, and in telephone calls threatened to report the elder to DWP for, as he calls it ‘benefit fraud'. Indeed, the information the younger brother has obtained, has been done by way of threatening texts/phone calls which may even amount to blackmail or an offence of harassment, at least. My 1st query is if the younger brother goes ahead and reports sibling to DWP, how does the fact, the way he has obtained information/intelligence/evidence affect any potential prosecution? Could the way the younger brother has 'handled' the situation and obtained information, make this situation difficult for DWP to prosecute as the information/evidence was obtained unfairly (to the say the least), and as I think illegally, which could taint any evidence that the DWP seek to rely upon? If it is the case, that because of the way intelligence/evidence has been obtained by the potential DWP informant, and thus making any prosecution difficult, this would obviously put the eldest’s mind at rest, and will obtain further legal advice, if such a need arises.
