The head of the Kobe Yamaguchi-gumi gangster group was served a fresh arrest warrant Friday in connection with a scuffle at the office of a different yakuza group in Kyoto in January.

Kunio Inoue, 68, heads the breakaway group of yakuza formed in 2015 by defectors from Yamaguchi-gumi, Japan's most powerful underworld group. He was previously arrested on suspicion of fraud for a mobile phone that was purchased under someone else's name on June 6.

On Friday, Kobe District Public Prosecutor's Office moved Inoue from a police station in Hyogo Prefecture, where he had been questioned over the fraud allegation, to the Kyoto Prefectural Police via a police car, without concluding the fraud case.
