Two male nurses in San Diego are under investigation after graphic home surveillance videos captured them apparently engaging in sex acts with a 98-year-old bedridden stroke patient and with each other.

California state officials are now working to revoke the licenses issued to nurses Russel Torralba and Alfredo V. Ruiz, XETV reported.

Russ Heimerich, a spokesman for the state Department of Consumer Affairs, told the San Diego Union Tribune that the video "appears to show very egregious behavior".

The home video shows the pair dressed in blue nurse uniforms fondling one another and touching the hand and face of their helpless female patient. An attorney said that in another clip, one of the nurses places the elderly patient's hand inside his pants.

"I don't know if we've ever had a case that has a video like this. We are working to shut them down," Heimerich said.

The video was just one of several taped last year. The patient's family had installed security cameras in her home to keep an eye on the care provided by private 12-hour nurses hired through a company called AMS Home Care Solutions, according to family lawyer William Berman.

"What they saw was horrific," said Berman. "These acts are unfathomable."

Berman said while the paralyzed female patient, who was not identified, is unable to call for help, she is conscious of herself and her surroundings.

Nurses Torralba and Ruiz had been hired at a rate of $1,300 a day, U-T San Diego reported.

The city's district attorney's office is currently reviewing the case for possible criminal charges, according to XETV.

Both the nurses have now been banned from working as in-home health providers, but they are still allowed to work in a hospital setting, pending the outcome of the hearing next week.
