SEOUL -- South Korean police were reviewing a raid on President Yoon Suk-yeol's residence as part of the investigation into Yoon's alleged insurrection charge over his martial law declaration, Yonhap news agency said Friday.

An unidentified official with the National Office of Investigation (NOI) was quoted as saying that the raid on the presidential residence was in the "reviewing stage" while a search warrant against Yoon for phone call details was being reviewed.

The police were also reviewing whether to seek an arrest warrant against Yoon, local broadcaster YTN reported.

A group of police investigators on Wednesday attempted to raid Yoon's office, but security service agents blocked the entry for security reasons.

Yoon was named as a suspect in the alleged insurrection charge over his declaration of an emergency martial law on the night of Dec. 3, which the National Assembly repealed hours later.

The opposition parties, including the main liberal Democratic Party, on Thursday submitted the second impeachment motion against Yoon after the first one was scrapped last Saturday.
