Hello my name is ***** ***** I will help you.
Has your brother got anything to do with your new work?
They know you are all related?
Ok - it makes no difference then, you havent done anything wrong.
If he does something illegal, unless you were involved or have knowledge then it would not effect you whatsoever. So unless that happens you would not be implicated or under suspicion.
In any event if he did steal something then you would NOT have to pay it back - its nothing to do with you.
Its all to do with him
Can I clarify anything for you about this today please?
