GUADALUPE, Ariz. -- An illegal immigrant has been arrested on suspicion of raping and kidnapping a 15-year-old girl at her Guadalupe home, Maricopa County sheriff's deputies said.

The MCSO Special Victims Unit arrested Jose Dolores Montoya Sanchez, 24.

Sanchez was booked into the Maricopa County jail late Wednesday on one count of sexual assault, one count of kidnapping and two counts sexual abuse.

Sheriff's deputies said they began investigating the case when the victim disclosed that Sanchez sexually assaulted her at a Guadalupe home.

The 15-year-old was immediately taken to a local hospital for medical treatment, MCSO said. A forensic evaluation confirmed an assault, according to sheriff's investigators.

Sheriff's deputies said Sanchez has been in the country illegally for the past 10 years.

"This suspect sexually assaulted a young innocent girl and this is yet another example of a violent crime committed by an illegal alien in Maricopa County," Sheriff Joe Arpaio said. "The deputies working in Guadalupe did a professional and thorough investigation."
