Why would you claim DLA for a dodgy reason (you have an issue but not as bad as you claim, as otherwise you wouldnt get the money) and then coach a sports team, or run a marathon or do a window cleaning round or labouring or hod carrying......
Why?
If you claim your bad back is so painful you cant dress yourself, why would you then do one of the above AND tell your team/colleagues/customers about your claim?
ANDDDDD why would you then be surprised that you got taken to court for fraud and blame the person/people that dobbed you in?
This has just happened to someone I know (not a friend, through an old job) and they seem to believe that it isnt their fault but the fault of the whistleblower!
If you are going to commit benefit fraud, at least try to be subtle about it!
