Japanese man jailed for internet hit

A Japanese man has been sentenced to life in jail for killing a 76-year-old man on behalf of the victim's son and grandson who had placed an order for his murder on the internet.

Naoya Katayama, 36, killed wheelchair-bound Tsutomu Nomoto by hitting him with a hammer, for which he was reportedly paid 2 million yen ($28,800).

The defence argued that Katayama had only sought to help other people by fulfilling the murder request.
