    BEIJING, June 8 (Xinhuanet) -- The on-again, off-again jail time sentence of Paris Hilton may be on again following her release to house arrest Thursday for an undisclosed medical condition. The judge who put her in jail for violating her reckless-driving probation ordered her into court to decide if she should go back behind bars.

    Hilton must report to court at 9 a.m. Friday, Superior Court spokesman Allan Parachini told The Associated Press.

    "My understanding is she will be brought in in a sheriff's vehicle from her home," Parachini said.

    Hilton was sent home from the Los Angeles County jail's Lynwood lockup shortly after 2 a.m. in a surprising reduction to her original 45-day sentence. She was ordered to finish her sentence under house arrest, meaning she could not leave her four-bedroom, three-bath home in the Hollywood Hills until next month.

    City Attorney Rocky Delgadillo complained he learned of her release the same way as almost everyone else ¡ª through news reports.

    Late Thursday he filed a petition questioning whether Sheriff Lee Baca should be held in contempt of court for releasing Hilton ¡ª and demanding that she be held in custody. Superior Court Judge Michael T. Sauer's decision to haul Hilton back to the courtroom came shortly after.

    "It is the city attorney's position that the decision on whether or not Ms. Hilton should be released early and placed on electronic monitoring should be made by Judge Sauer and not the Sheriff's Department," said Jeffrey Isaacs of the city attorney's office.

    Sauer himself had expressed his unhappiness with Hilton's release before Delgadillo asked him to return her to court. When he sentenced Hilton to jail last month, he ruled specifically that she could not serve her sentence at home under electronic monitoring.
