Former boxer Iwao Hakamada, 89, was exonerated of a 1966 quadruple murder. He received US$83 for each day he wrongly spent in detention.

Nearly 50 years on death row had inflicted "extremely severe" mental and physical pain on Iwao Hakamata, a judge said.

An 89-year-old Japanese man who spent nearly half a century on death row for a 1966 quadruple murder before being exonerated last year was awarded a record $1.44 million in compensation on Tuesday.
