South Korea's Yoon Suk Yeol has become the country's first sitting president to be arrested, ending a weeks-long standoff between investigators and his personal security. Yoon, whose failed attempt to impose martial law plunged the country into turmoil and saw him impeached by parliament, is being investigated on charges of insurrection.

Yoon was brought into custody about three hours after hundreds of law enforcement officers entered the residential compound in their second attempt to detain him.
