SEOUL - South Korea's police banned former prime minister Han Duck-soo, and Choi Sang-mok, former deputy prime minister for economic affairs, for alleged insurrection charges, multiple media outlets said on Tuesday.

Han and Choi have been under investigation as suspects of insurrection and prevented from leaving the country in the middle of this month.

The police special investigative unit summoned Han and Choi as well as Lee Sang-min, former interior minister who was prohibited from leaving the country last December, for questioning on Monday.

The three former government officials were suspected of being involved in the botched martial law bid by former president Yoon Suk-yeol, who was removed from office in April.
