The lawsuit was filed on behalf of American citizen Sabri Benkahla. Check out these facts:

....[Benkahla is] a graduate of George Mason University. Benkahla was studying Islamic law and jurisprudence in Saudi Arabia in 2003 when he was abducted at gunpoint by the Saudi secret police the night before his wedding, transferred to the custody of the FBI, flown back to America and charged with supplying services to the Taliban and using a firearm in connection with a crime of violence. After a bench trial, U.S. District Court Judge Leonie Brinkema found him not guilty. Brinkema called his arrest and transfer to American authorities "a Kafkaesque situation."

It gets worse:

Less than a month later, however, the government – not satisfied with Benkahla's acquittal – forced him to testify before a federal grand jury. He was accused and convicted of perjury, despite the fact that most of the allegedly false statements he was accused of making involved the same subject matter that served as the basis for his previous trial. Benkahla was sentenced to 121 months in prison, but even his sentencing judge, U.S. District Court Judge James C. Cacheris, declared unequivocally that "Sabri Benkahla is not a terrorist," highlighted his "model citizenry," and stated that the chances of Benkahla ever committing another crime were "infinitesimal."

Benkahla was tranferred to the CMU in Terre Haute. The complaint is available here.
