It is a friend of mine - the employer has asserted he burnt his arm (3rd degree) deliberately (in the absence of a mechanical/technical explanation). He denies this. He is an ex-soldier (as am I) who served in the Gulf. In the past self harming has been when depressed/at times of great stress. This accident occured when he was happy and engaged to be married. I just wanted to know if the employer might be right and my faith in him might be misplaced!
