A joint military–police task force has raided the homes and offices of three civilians accused of flying drones into North Korea. 

The task force said on Wednesday that it began search-and-seizure operations at around 8 a.m. at the homes and offices of three individuals, including those surnamed Oh and Jang, whom it suspects violated the Aviation Safety Act.

The task force said it plans to analyze seized materials and question the suspects.

The raid came five days after Oh claimed responsibility for flying the drones in a Channel A interview. 

Oh said he had asked Jang to manufacture the drones, and Yonhap reported Wednesday that the two worked together as contract employees at the presidential office in Seoul's Yongsan District under former President Yoon Suk Yeol.

Newstapa reported Monday that Oh operates two online media outlets focused on North Korea and that an official from the Korea Defense Intelligence Command allegedly used the outlets as front companies for covert operations, providing them with roughly ten million won in operating funds.
