The Japanese prime minister Fumio Kishida was evacuated unharmed on Saturday after what appeared to be a smoke bomb was thrown at him.
According to public broadcaster NHK and government officials, a masked male suspect was arrested at the scene by police at the port of Saikazaki in Wakayama prefecture. Kishida was on the campaign trail ahead of local elections.
Hirokazu Matsuno, the chief cabinet secretary, condemned the incident and said the police were investigating the motive of the suspect, reported to be a 24-year-old man, after he was arrested on charges of “forcible obstruction of business”. Local police officials declined to comment.
