Lost stars Michelle Rodriguez and Cynthia Watros were arrested Wednesday night for driving under the influence of alcohol, PEOPLE has learned.
Rodriguez, 27, who plays Ana Lucia, and Watros, 37, who plays Libby, were arrested for DUI on the island of Oahu in Hawaii where the show is filming its second season.
"They were arrested just before midnight without incident, and both women were driving their own vehicles," Capt. Frank Fujii of the Honolulu Police Department tells PEOPLE. No other details of the arrest were available.
The actresses both posted bail early the next morning, according a police source. Representatives of both actresses and the show had no comment.
This wouldn't be the first driving-related mishap for Rodriguez, who last year pleaded no contest to three misdemeanors (a hit and run, driving with a suspended license, and driving under the influence) stemming from two 2003 auto incidents in L.A. She was sentenced to 48 hours in jail, community service and treatment in a 30-day alcohol program.
Formal charges are expected to be filed against both Rodriguez and Watros on Dec. 29 at the Kaneohe District Court.
