South Korea’s jailed ex-President Yoon Suk Yeol again refused to attend questioning by investigators Friday, using a new method to resist: He took off his prison uniform and lay down on the floor at his detention room.

SEOUL (Reuters) -South Korea's ousted President Yoon Suk Yeol, who is in detention while on trial and facing various criminal probes, lay on the floor of his cell on Friday and refused to leave it for questioning, a spokesperson for a special prosecutor said.

Disgraced former South Korean President Yoon Suk-yeol has been indicted over his declaration of martial law last year as investigators widened an insurrection probe. The prosecution indicted Yoon on charges including abuse of power and obstruction of special official duties, prosecutor Park Ji-young told reporters on Saturday.
