DENVER (AP) — A Saudi national who was denied a request to serve out the reminder of a Colorado prison sentence in his home country is suing prosecutors and FBI agents for defamation.

In a federal lawsuit filed Friday, Homaidan al-Turki says the officials claimed he had terrorist ties and mis-characterized his crimes in order to derail his transfer.

Then-prisons director Tom Clements initially approved al-Turki’s transfer but reversed his decision in March 2013, one week before he was killed at his home in Monument.

The lawsuit says Clements changed his mind because the officials said al-Turki was a national security threat. Al-Turki says the officials then falsely leaked the theory that he had a role in Clements’ killing.

Al-Turki is serving an eight-years-to-life sentence in Beaumont, Texas, for unlawful sexual contact by use of force.
