"I was informed of the incident early in the morning," Villaraigosa said. "What I don't want to do is rush to judgment. She's worked for us for two years, never had problems in the past.
"There are always going to be situations where an individual gets into trouble or problems. That doesn't reflect on the rest of her colleagues."
According to Los Angeles Police Department officials, the couple was fighting outside the nightclub when officers arrived. When officers approached Navarro, he allegedly attacked one of them.
"The husband actually attacked one of our officers, grabbing his wrist, trying to put it behind his back or twist it in some manner," said Officer Karen Rayner of the LAPD.
Police said that's when Martinez-Navarro jumped on the back of one of the officers and started hitting him.
"There was a small use of force to take her into custody and they were both booked on battery on a police officer," Rayner said.
She posted $20,000 bail and was released about 2:30 p.m. Sunday.
Martinez-Navarro is a program manager for the city's gang reduction program in the Rampart area. Officials said she was placed on administrative leave.
Attempts to reach Martinez-Navarro were unsuccessful.
