The 41-year-old accused had fired two bullets at Shinzo Abe.

The man who assassinated former Japanese Prime Minister Shinzo Abe on Friday believed that Shinzo Abe belonged to a religious group that bankrupted his mother.

He used to blame this group for his mother's poor financial condition.

On Saturday, police informed local media that they had been planning to attack Abe with a homemade gun for months.

The suspect, who attacked Shinzo Abe during an election rally in the middle of the street, has been identified as 41-year-old Tetsuya Yamagami.

In the videos that have surfaced, it can be seen that a man with spectacles, a gray haired man in a gray T-shirt and beige colored pants comes very close to Abe and fires two bullets one after the other.

He carried out the murder with a 40 cm gun, which according to local media was made by him himself.

His gun was wrapped in black tape.

As soon as he opened fire, the policemen caught him there.

According to a Reuters report, after talking to the neighbors of the accused, it was found that he lived alone and silent.

The Kyodo News Agency, citing investigative sources, said it believed Abe had supported a religious group to which his mother had gone bankrupt by donating to her. 

Kyodo and other local media outlets quoted police as saying that the killer said during interrogation that "my mother had fallen in love with a religious group, and I didn't like it at all."

Nara Police has not given any explanation on this.

The name of this religious group has not even appeared in the media.

It is known that Yamagami had ordered many parts online to make the gun and had been preparing to carry out the murder for months.

He even went to Shinzo Abe's other campaigns looking for opportunities.

A day before the day of the murder, he had gone 200 km away to attend a campaign.
