Police arrested the former head of a Tokyo nonprofit organization Thursday on suspicion of swindling group members through an investment scheme.

Investigators from Tokyo and Hiroshima Prefecture arrested 62-year-old Akira Matsui, who headed the Yamabikokai group, and four other people over fraud allegations involving some 13 million yen collected from four group members between September 2002 and March 2003.

Among the other suspects are 45-year-old Takafumi Negoro of Kawasaki, who was a Yamabikokai member, and Yoshinori Sadasue, 56, of the city of Fukuoka.
