When Folsom police officers responded to a call involving an alleged intoxicated man and a physical altercation, they discovered that the suspect was a fellow officer.

Off-duty Officer Evan Fardanesh, 34, had been at a restaurant located along the 25000 block of Blue Ravine Road where, allegedly, he had an altercation with another patron, according to a statement issued by Folsom Police Public Information Officer Michelle Beattie.

Beattie said that the patron called 911. Upon arrival, police contacted the alleged victim, who told them that he’d placed Fardanesh under citizen’s arrest.

Fardanesh was in his vehicle when his fellow officers found him. He was arrested on suspicion of driving under the influence and battery.

Fardanesh’s blood-alcohol level was reportedly .19, which is more than twice the legal limit, according to the statement.

No injuries from the altercation were reported, according to Beattie.

Fardanesh was not booked into Sacramento County Jail when he was arrested, she said.

“He was released to a responsible party,” she said. “He didn’t receive special treatment. That is an option that is available to us (and is) something we do with some DUI arrests.”

She said the citation and release of the officer, “is the same as an arrest.”

Fardanesh, a nine-year veteran of the department, is on paid administrative leave pending an internal affairs investigation.

“(The case) has been turned over to the Sacramento County District Attorney’s office. They will determine whether or not to prosecute,” Beattie said.
