Colorado prison officials say they didn't find enough evidence to take action against a Saudi inmate who was accused of trying to have another inmate killed.
Officials said Tuesday that no criminal charges were filed and no internal discipline was pursued against Homaidan al-Turki.
Al-Turki is serving prison time after he was convicted in 2006 of sexually assaulting his housekeeper and treating her as a virtual slave when he lived in the Denver area.
Prosecutors revealed the allegation last week as al-Turki and Saudi officials asked a judge to allow al-Turki to serve his sentence in his home country. The judge hasn't issued a decision.
Prosecutors are fighting the move.
Neither prosecutors nor al-Turki's lawyer immediately returned calls Tuesday. Al-Turki's lawyer has said the prison allegation was baseless.
