Schoolboy stabbed baby brother '17 times in cot'

A 13-year-old boy is in secure custody after a court heard how he killed his baby brother by stabbing him 17 times and cutting off his left hand.

Bristol Crown Court was told how the boy, who suffers from a serious psychiatric illness, had an "appalling" and "wretched" upbringing leading up to the killing on January 19, last year.
