Police on Friday arrested Tadahiro Ando, who resigned as Miyazaki governor earlier in the week after a no-confidence motion, for allegedly collaborating with other officials in rigging bids for public works projects.
Miyazaki became the third prefecture in just over a month to have its governor arrested for alleged involvement in bid-rigging.
The Miyazaki Prefectural Police served the arrest warrant on Ando after they had brought him in for questioning on a voluntary basis.
