All of the senior prosecutors who led investigations involving the presidential office and ruling camp figures have been replaced.

The Justice Ministry on Thursday announced a reshuffle of over 700 senior and junior prosecutors effective February third, replacing two deputies at the Seoul Central District Prosecutors' Office.

Shin Bong-su and Song Kyung-ho, who were in charge of probes into alleged top office election-meddling and corruption by former Justice Minister Cho Kuk and his family, respectively, have been reassigned.

Hong Seung-wook, another deputy at the Seoul Eastern District Prosecutors' Office who led the investigation into the top office's alleged intervention in an inspection involving a former Busan vice mayor, was also replaced.

The three prosecutors were each appointed to head regional offices outside Seoul.

The ministry said the reshuffle was part of the Moon Jae-in administration's prosecutorial reforms to reduce the size of the state agency's direct investigation departments.
