Khieu Samphan was lying on his sickbed when the police finally arrived.
The former Khmer Rouge head of state, who was recuperating from a stroke, knew this day would eventually come, even if he privately hoped it never would.
When the officers arrived at Phnom Penh's Calmet Hospital on Monday and charged him with war crimes and crimes against humanity, he was not surprised.
The 76-year-old was arrested and transferred from his hospital bed to a detention cell on the site where Cambodia's UN-backed tribunal is preparing to bring Khmer Rouge leaders to justice.
Khieu Samphan has spent most of the past 30 years denying responsibility for the deaths of 1.7 million Cambodians during the Khmer Rouge's reign of madness from 1975 to 1979.
He even asked Cambodians to put the past behind them.
