Police raided the National Election Commission on June 11 over ballot shortages that disrupted voting at 26 polling stations during the June 3 local elections, as protests demanding a rerun continue.
Police conducted a 13-hour search of the commission headquarters in Gwacheon and seven Seoul offices, deploying more than 100 investigators. They are probing possible election law violations and dereliction of duty, with former Chairman Rho Tae-ak named as a suspect.
The commission said shortages hit 14 stations in Songpa District. Acting Chairman Wi Cheol-hwan apologized for lowering the printing ratio to 50 percent and noted a separate vote-counting error in Jeonbuk that did not alter results.
The National Assembly began steps toward a parliamentary investigation, with both major parties submitting requests. Prime Minister Kim Min-seok urged a swift probe. President Lee Jae Myung's approval rating fell nine points to 57 percent.
