A judge says Lindsay Lohan is in violation of her probation after encountering problems during her community service.
Superior Court Judge Stephanie Sautner said during a hearing Wednesday attended by the actress that her ousting from a community service assignment at a women's shelter was a cause to revoke probation.
A city prosecutor said Lohan should be jailed.
Lohan has started serving hours with the American Red Cross, but Sautner said that would not count toward her probation because it was not part of her sentence.
Sautner said Lohan would be entitled to a hearing before being sentenced to jail.
It's the latest legal problem for the 25-year-old Lohan, who remains on probation for a 2007 drunken driving case and a misdemeanor theft case this year.
