A 47-year-old Japanese man wanted by Tokyo police on suspicion of fraudulently receiving government coronavirus subsidies was arrested in Indonesia for overstaying his visa, Indonesian police said Wednesday.

Mitsuhiro Taniguchi and members of his family are suspected of fraudulently obtaining more than ¥960 million ($7.22 million) in government subsidies meant for small firms reeling from the pandemic.

Police had placed Taniguchi on a wanted list, suspecting he may be the ringleader, but his whereabouts were unknown after he left Japan for Indonesia in October 2020.

Indonesian police arrested him Tuesday night in the Lampung provincial capital of Bandarlampung on suspicion of overstaying his visa after Japan revoked his passport, national police spokesman Gatot Repli Handoko told Kyodo News.

Taniguchi is suspected of working with others, including his ex-wife and eldest son, to submit a total of 1,780 false applications between May and September 2020, resulting in him receiving around ¥960 million. Police believe it may be the largest ever case of benefit fraud in Japan involving just one group.

Last month, the Tokyo Metropolitan Police Department arrested three people — Taniguchi's 45-year-old ex-wife, Rie, his eldest son Daiki, 22, as well as his 21-year-old son — on suspicion of defrauding the government of ¥3 million in COVID-19 subsidies.

The scam reportedly came to light in August 2020, when the office allocating the subsidies contacted Tokyo police.

The suspects allegedly collected false applicants via social media and seminars, then processed applications on their behalf using the names of individuals and corporations across 36 prefectures.
