Japan’s National Police Agency chief, Itaru Nakamura, has announced his resignation after an investigation confirmed shortcomings in the security plans for the assassinated former Prime Minister Shinzo Abe.
Nakamura while announcing his resignation to reporters on Thursday also said he will take responsibility for the murder of the former Prime Minister, Reuters reports.
He also cited the need for a "fresh start" for the organisation and its security duties.
Itaru told reporters: “There were shortcomings in the security plans and the risk assessments on which they were based, and direction from the field commander was insufficient,”
"In the process of verifying our new security plan, we have come to realise that our security duties would need a fresh start," Nakamura added.
"To mark our fresh start with a new security plan, it is only natural for us to build a new organisation," he said.
Itaru Nakamura is the most senior official to step down in connection with Abe's assassination at a campaign rally in the western city of Nara on July 8, where experts have said security was seriously flawed.
Nara police chief Tomoaki Onizuka also resigned.
"As the chief of police with security responsibility in this prefecture, I am painfully aware of my responsibility for causing a serious situation," he told a news conference.
Japanese officials, including Prime Minister Fumio Kishida, have acknowledged flaws in the security around Abe's appearance at the election campaign event.
The National Police Agency previously told Reuters the killing had been the result of police failing to fulfil their responsibility, adding that it had set up a team to review security and protection measures and develop preventive steps
The suspected assassin, arrested at the scene moments after the shooting, is undergoing psychiatric evaluation, Japanese media reported last month.
