The chief of the Defense Intelligence Command suspected of taking part in martial law operations has been formally arrested Wednesday, an anti-corruption investigation body probing the martial law decree said.

Maj. Gen. Moon Sang-ho was placed under arrest at 12:20 p.m., according to the Corruption Investigation Office for High-ranking Officials.

Moon is suspected of sending troops in his command to the National Election Commission's office in Gwacheon, just south of Seoul, on Dec. 3 after President Yoon Suk Yeol declared martial law.

He is also suspected of discussing martial law operations with Noh Sang-won, a former defense intelligence commander, alongside two other subordinates at a burger franchise in Gyeonggi Province two days ahead of Yoon's martial law imposition.

A court hearing on whether to formally arrest Noh, the former commander, is scheduled for 3 p.m. Noh has expressed his intent not to attend it. (Yonhap)
