OSAKA -- Police on Monday raided the Kinki Postal Administration Office following the arrest of its head official Sunday in connection with a vote-rigging scandal.
Tsuyoshi Mishima, 59, was arrested on suspicion of urging some 100 postmasters to join a support group for Kenji Koso, a newly elected lawmaker in the House of Councilors, during a March meeting of special post office chiefs in Osaka.
He is also suspected of ordering various activities aimed at boosting support for Koso, police said.
