Lindsay Lohan is a most wanted woman ... because TMZ has learned a SECOND police department wants a chitchat with the actress to determine if she committed a crime by lying to cops.
Law enforcement sources tell us ... Santa Monica police detectives have been trying to get in touch with Lindsay to ask her questions about a car crash last June, when she slammed into a big rig on the Pacific Coast Highway. Sources say Lindsay's lawyer, Shawn Holley, called the station and complained that cops should not be calling Lindsay directly because she has an attorney.
We broke the story ... Lindsay lied to cops when she told them she was NOT the driver, but a passenger. Cops are convinced Lindsay was indeed behind the wheel and are now investigating.
Sources tell us the follow-up questions relate to Lindsay's alleged lying to cops -- which is a crime punishable by 1 year in jail. We're told the case will be referred to prosecutors. It will also be sent to the L.A. City Attorney for a possible probation violation in her necklace conviction.
And, as we first reported yesterday, the LAPD is investigating Lindsay on another front. She's now a suspect in a $100,000 theft of watches and sunglasses at at Hollywood Hills home, and cops want to speak with her STAT. Lindsay's lawyer shut detectives down, saying no way would she cooperate.
Lindsay Lohan is now formally a suspect in the theft of $100,000 worth of watches and sunglasses ... law enforcement sources tell TMZ.
As TMZ first reported, Lindsay was at the Hollywood Hills home of Sam Magid a week ago when Sam called the LAPD and reported a jewelry theft. We're told Lindsay has been at the house frequently, including at an all-night house party a week ago Sunday.
Law enforcement sources tell us ... Lindsay and her assistant Gavin Doyle are both suspects in the theft.
Now here's the twist ... We're told Sam has recanted his story and now says nothing was stolen. But our sources say cops are not closing out the investigation because they believe they have independent witnesses who can finger Lindsay and Gavin as the thieves.
Sources tell us ... LAPD detectives contacted the lawyer for Lindsay and Gavin today, asking for an interview with the two suspects but the lawyer rejected the request.
It's unclear why Sam -- who is insanely wealthy -- suddenly changed his tune.
One final thing ... This is really bad news for Lindsay, because she's on probation for the theft case involving the necklace at a Venice jewelry store. She could go to jail if she violates probation by stealing more jewelry.
