LOS ANGELES � Los Angeles police say they have arrested a woman who officers saw try to attack Simon Cowell�s ex-girlfriend outside the venue where �American Idol� is taped.

Officer Norma Eisenman says officers arrested Janice Thibodeaux (Ti-bo-DOH�) after they saw her try to choke �Extra� correspondent Terri Seymour. She is being held on nearly $54,000 bail for suspicion of felony battery.
Police did not identify Seymour, but a story posted on the �Extra� Web site confirmed the encounter. Seymour refused medical treatment after the incident.
Eisenman says Thibodeaux asked Seymour if she was Cowell�s ex-girlfriend before trying to choke her. The 33-year-old ran from officers for a short distance before being arrested.
