A man accused of kidnapping an Oregon woman and locking her in a makeshift cell is scheduled to face trial in October.

Negasi Zuberi, a 29-year-old married father, was arrested in July after a woman escaped from a makeshift cinder block cell in his Klamath Falls home, where she told authorities Zuberi held her hostage and sexually assaulted her.

"According to the complaint, this woman was kidnapped, chained, sexually assaulted, and locked in a cinder block cell," FBI Portland Assistant Special Agent in Charge Stephanie Shark said in a statement earlier this month. "Police say she beat the door with her hands until they were bloody in order to break free. Her quick thinking and will to survive may have saved other women from a similar nightmare."

Zuberi pleaded not guilty to charges of kidnapping and transportation with intent to engage in sexual activity. His trial date is set for Oct. 17, and a status hearing is scheduled for Sept. 25.

The FBI believes Zuberi, who has ties to 10 different states over the last 10 years, may be involved in additional attacks and is asking any other victims who may have encountered the suspect to contact authorities. The states other than Oregon may include California, Washington, Colorado, Utah, Florida, New York, New Jersey, Alabama and Nevada, the FBI said.

Just before his arrest on July 15, Zuberi allegedly traveled from Klamath Falls to Seattle – a seven-and-a-half-hour drive – and solicited services from the victim, a sex worker. Zuberi then posed as a police officer and restrained the woman in handcuffs and leg irons while pointing a Taser at her, the FBI said.

The suspect drove the victim 450 miles back to his Oregon home and allegedly raped her during the trip back, according to the affidavit. 

He then allegedly held her hostage in the cell inside his garage, which had a door installed in reverse so that it could not be opened from the inside, according to an affidavit.

The victim "briefly slept and awoke to the realization that she would likely die if she did not attempt to escape," the affidavit states. She "repeatedly banged on the door and was able to break the door open and escape the room. Once outside of the cell, she observed… Zuberi's vehicle parked in the garage, opened the vehicle door, observed the handgun, retrieved it, and fled."

Once outside Zuberi's home, she flagged down a passing driver, who called 911.

The suspect "refused to exit the vehicle and cut himself with a sharp object causing him to bleed profusely" and "also attempted to destroy his phone" before police eventually took him into custody.

The 29-year-old sometimes went by different aliases, including "Sakima," "Justin Hyche" and "Justi Koussai."
