A Fort Benning soldier was arrested Monday for allegedly raping a 19-year-old woman in Auburn, Ala., in May, officials said.

Alexander Hernandez, 23, faces a charge of rape in the first degree, according to Auburn police.

A Fort Benning spokeswoman confirmed that Hernandez is a soldier assigned to the 75th Ranger Regiment Military Intelligence Battalion.

“We take allegations of potential criminal activity seriously. The Regiment is cooperating fully with local law enforcement's investigation,” spokeswoman Tracy Bailey told AJC.com.

Hernandez is an acquaintance of the victim, police said.

The victim, who was not identified, was found lying unconscious on Engineering Drive on Auburn University’s campus May 12 at about 2 a.m. Police did not say whether she is a student.

An investigation using DNA evidence determined that Hernandez sexually assaulted the victim, police said.

After a warrant was put out for his arrest, Hernandez turned himself in. He was held on a $100,000 bond at Lee County Jail.
