SEOUL — A special counsel team on Tuesday searched a handball arena that served as a vote-counting center during the June 3 local elections, part of an investigation into an unprecedented shortage of ballots that forced some voters to leave without casting ballots. Special counsel Lee Tae-han sent investigators to execute a search-and-seizure warrant at the Olympic Park Handball Gymnasium in southeastern Seoul to secure election records and surveillance camera footage, according to the special counsel's office.
