Wayne Jowett died a month after the mistake.

A father has called the legal system "ridiculous" after the doctor responsible for the injection which killed his son walked free from jail.

Dr Feda Mulhem was sentenced to eight months after admitting unlawfully killing cancer patient Wayne Jowett and a further 10 months on five unrelated assault charges. But having already served 11 months on remand - more than half his sentence - Mulhem, of Stanley Road, Leicester, was released from custody.

Mr Jowett, 18, died after a toxic cancer drug was wrongly injected into his spine at Nottingham's Queen's Medical Centre in 2001.
