LOS ANGELES - (AP) - Several bailiffs led Lindsay Lohan from a LosAngeles courtroom on Friday after a judge who heard evidenceagainst the actress in a theft case sentenced her to 120 days injail for a probation violation.

The actress, who often conferred with her attorney throughout apreliminary hearing, showed little reaction as Los Angeles SuperiorCourt Judge Stephanie Sautner gave her ruling.

Lohan's attorney, Shawn Holley, said she will appeal, allowingthe Lohan, 24, to post bail, which was set at $75,000.

The "Mean Girls" star also was ordered to serve more than 400hours of community service, including 300 hours at a women'scenter.

It will be Lohan's fourth jail stint.

The ruling came after Sautner reduced Lohan's grand theft casedown to a misdemeanor and after prosecutors gave their case againstthe actress.

Sautner ruled that prosecutors had shown that Lohan violated herprobation on a 2007 drunken driving case. The judge refused todismiss the theft case against Lohan, who entered a not guilty pleaFriday.

"I see the intent here," Sautner said. "I see a level ofbrazenness with `Let me see what I can get away with here."'

But Sautner also said she often sees more serious cases that getreduced to lesser charges and that she wanted to give the Lohan"an opportunity."
