Judge to Lindsay Lohan: 'Don't push your luck'

Lindsay Lohan pleaded not guilty Wednesday to one count of felony grand theft of personal property in connection with a $2,500 necklace taken from a Venice, Calif., jewelry store on Jan. 22.

Judge Keith Schwartz set bail at $20,000 and revoked Lohan's existing probation on a 2007 DUI case, setting a separate $20,000 bail for that.

In the brief hearing, which ended with Lohan being remanded to sheriff's deputies for processing, Schwartz sternly addressed the actress.

"You're in a different situation now that a felony has been filed against you," he said. "While this case is percolating, until a resolution is reached, if you violate the law I will remand you and set no bail. . . . You need to follow the laws just like everybody else."

He added: "Don't push your luck. Because I'm telling you . . . things will be different."

Schwartz scheduled a Feb. 23 hearing on the revoked probation.

During the proceeding, prosecutor Danette Meyers noted someone in Lohan's camp had sent flowers to the jewelry store owners, Geoffrey and Sofia Kaman. Schwartz ordered that Lohan and her representatives have no contact with them. Lohan, 24, arrived at the Airport Superior Court in Los Angeles at 1:08 p.m. for her scheduled 1:30 arraignment wearing a white minidress.

The district attorney believes the alleged theft is part of a pattern, sources told TMZ.com, following suspicions that Lohan had taken a $35,000 Rolex from an acquaintance in 2010, a $400,000 necklace from an Elle magazine photo shoot in 2009 and a $12,000 mink coat from a Manhattan nightclub in 2008. She was not prosecuted in any of these cases.

Shortly after the necklace went missing, the owners of the Kamofie & Co. jewelry store gave the Los Angeles Police Department surveillance video of Lohan wearing the piece.
