A prisoner told investigators she was forced to perform a sex act on a Tucson police officer after being arrested in August, according to police documents.
The allegations resulted in the department’s internal affairs office conducting a criminal and administrative investigation.
Benjamin Gaballa, who was hired in September 2012 and fired Aug. 22, is facing two counts each of sexual abuse and sexual assault, Sgt. Chris Widmer, a department spokesman, has said.
On Sept. 25, Gaballa was taken into custody at police headquarters and then booked into the Pima County jail, Widmer said.
The woman said the act took place before she was booked into the Pima County jail Aug. 20.
She said she was arrested at her home at about 8:30 a.m., handcuffed and placed into Gaballa’s patrol car. Reports released to the public do not say why she was arrested.
The woman told authorities Gaballa then drove for about 30 minutes before going into a parking garage off North Campbell Avenue and East Grant Road.
She said Gaballa took off the handcuffs, and that the act took place outside the patrol car on the passenger’s side near the rear of the vehicle, documents state.
The woman said she then ran from Gaballa, who chased her and caught her. She said they struggled before Gaballa handcuffed her and placed her back into the squad car and took her to jail.
Investigators interviewed a barber who witnessed an officer chasing a woman, capturing her and handcuffing her, documents state.
After the woman was booked into jail, she reported to jail personnel, who then notified Tucson police, that she was assaulted by Gaballa.
Investigators took the woman to Tucson Medical Center for an examination, and collected clothing and other evidence.
They also collected Gaballa’s clothing and DNA evidence, and searched his squad car for fingerprints and evidence, reports state.
A crime-scene specialist reported that a syringe with dry residue and a small amount of marijuana was found in Gaballa’s duty bag, the reports state.
“These items appeared to have evidentiary value to another case that he (Gaballa) had investigated where the evidence had not been submitted,” the documents say.
