A former naval chief Hwang Ki-chul

A former naval chief was summoned Tuesday for questioning over his alleged involvement in the graft scandal related to the country's indigenous salvage ship, investigators and military officers said.
The retired admiral, Hwang Ki-chul, is suspected of turning a blind eye to alleged corruption by his subordinates in 2009 over the selection of a winning bidder for the domestically built salvage ship Tongyeong, according to the investigators.
