A special counsel team raided the home of People Power Party(PPP) Rep. Yoon Sang-hyun on Tuesday as part of its ongoing investigation into corruption allegations surrounding former first lady Kim Keon-hee.

It marks the first time Rep. Yoon is being investigated in connection with the case.

A KBS report confirmed that the team led by special counsel Min Joong-ki carried out search and seizure operations at around 10 locations, including Yoon’s residence as well as his office at the National Assembly.

Investigators also raided the homes of former PPP lawmaker Kim Young-sun and former senior prosecutor Kim Sang-min.

In December last year, prosecutors indicted Kim, the former five-term lawmaker, along with Myung Tae-kyun, a political broker linked to former President Yoon Suk Yeol and his wife, on charges of violating the Political Funds Act during the 2022 parliamentary by-elections.

The special counsel team is expected to summon Kang Hye-kyung, the first informant in the case, as a witness for questioning as early as this week.
