SOUTH SAN FRANCISCO >> A Los Angeles County public defender was arrested on suspicion of assault and battery Monday after authorities said she drunkenly kicked a group of police officers during a tirade at San Francisco International Airport.

Monica Marie Jenkins, 36, pleaded not guilty in San Mateo County Court Tuesday, the day after SFO employees prevented her from boarding her flight to Los Angeles because they said she was too drunk to fly, District Attorney Steve Wagstaffe said. The woman reportedly became belligerent and refused suggestions to sober up and catch a later flight. Instead, she threatened to sue arriving officers and demanded to be taken to jail.

Police finally arrested on suspicion of being drunk in public after the woman broke out into song, screaming “1, 2, 3, 4, 5 o’clock rock” but somewhat fumbling the lyrics to Bill Haley & His Comets’ 1954 hit song “Rock Around the Clock.”

While they were escorting her from the gate, she kicked an officer and tried to kick another while continuously screaming profanities, according to reports.

Jenkins’ erratic behavior continued once in a patrol car, where she told officers, “Thank you for saving me,” and kept frantically asking about her missing purse because “it’s worth a lot of money.” She then calmed down and told police, “I’m not worried anymore — give me some cocaine.”

When that didn’t go well, she went back to being angry and again threatened to fight and sue the officers, Wagstaffe said. Upon arriving at the jail, she tried to bite a nurse who was attending to her booking.

Jenkins was released from jail after entering her plea and is scheduled to return to the Bay Area for a July 14 trial.
