Report: Lindsay Lohan a Suspect in Another Jewelry Theft -- and Her Latest Legal Problems Don't End There TMZ

Law enforcement authorities say actress Lindsay Lohan is formally a suspect in a recent theft of watches and sunglasses valued at $100,000, reports.

“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,” TMZ reported Monday. “Law enforcement sources tell us ... Lindsay and her assistant Gavin Doyle are both suspects in the theft.”

The report notes that Magid reportedly recanted his story and is now saying that nothing was stolen. However, sources cited in the story say the police are leaving the investigation open and have independent witnesses who identify Lohan and Doyle as the culprits.

Lohan remains on probation in a widely publicized previous theft case involving a necklace from a Venice jewelry store. Authorities were reportedly trying to set up an interview with Lohan and Doyle in the latest case.

In a separate incident, TMZ reports that Lohan is the focus of a probe by another police department for possibly lying to officers about a traffic collision a couple of months ago.

The website reports: “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.”

Authorities involved in the Santa Monica case are reportedly convinced that Lohan, who told police she was a passenger during the collision and was not driving the car, was in fact behind the wheel, the story reports.

“Sources tell us the follow-up questions relate to Lindsay's alleged lying to cops -- which is a crime punishable by one year in jail,” TMZ reports. “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.”
