Police investigating the assassination of Japan's ex-prime minister Shinzo Abe have said the suspect held a grudge against a "specific organization," APA reports citing BBC.
The alleged gunman, named Tetsuya Yamagami, 41, believed Abe was part of the group and shot him for that reason, they said, without naming the group.
Abe died in hospital on Friday morning after being shot while speaking at a political campaign event.
Yamagami has admitted to shooting him with a homemade gun, police said.
Abe was Japan's longest-serving prime minister and his death at the age of 67 has profoundly shocked a country where gun crime is very rare.
He was shot while campaigning for his former party, the Liberal Democratic Party (LDP), in the run-up to upper house parliamentary elections on Sunday.
