Murdered Prison Officer's family speaks

The family of murdered prison officer David Black have given their first interview. In it they pay tribute to a hard-working, honest and principled man and appeal for help in catching his killers. David Black was shot dead as he made his way to work in Maghaberry Jail four weeks ago. Dissident republicans have since suspended a so called dirty protest in the prison. It was being held in opposition to so-called strip searching ahead of visits.
