PHOENIX - A man contracted to transport prisoners across state lines was arrested Thursday in California, accused of sexually assaulting women in his custody.

The complaint and probable cause statement in the case say Eric Scott Kindley, 49, is accused of assaulting three prisoners on three different transports in his Dodge Caravan between January and May this year. Two of the transports were to Arizona -- one from California and the other from Alabama. The third was from Mississippi to New Mexico.

The Department of Justice said in a statement Friday that Kindley operates Special Operations Group 6, which is contracted by jails to transport inmates arrested on out-of-state warrants.

According to court documents, the victims said in each case, they were handcuffed and restrained, and Kindley took them to secluded locations before threatening and sexually assaulting them, threatening them with a gun.

The victims said he told them he'd get away with it because nobody would believe them if they spoke up, and he bragged about doing the same to other prisoners in previous transports.

Kindley had his initial appearance Friday in Sacramento, California, where a judge ordered he stay detained over the weekend. The complaint was issued in Phoenix, so he may be taken there for trial.
