    LOS ANGELES, June 8 (Xinhua) -- Hollywood socialite Paris Hilton is scheduled to be back in a Los Angeles courtroom Friday as prosecutors were angry with the jail authorities' decision to release her earlier and demanded her returning behind bars.

    Hilton's release on Thursday morning has sparked a public outcry, with hundreds of people telephoning, e-mailing and faxing local officials and prosecutors, calling her three-week-early departure from jail a case of preferential treatment for a Hollywood celebrity.

    The judge who sentenced Hilton ordered her back into court to consider whether the Los Angeles County Sheriff's Department acted improperly by allowing her to serve the rest of her sentence at home while wearing an ankle monitor.

    Sheriff Lee Baca, whose department runs the county's jail system, said the 26-year-old hotel chain heiress was released because of "a medical issue."

    According to a spokesman of the sheriff's department, the decision to release Hilton was made after "extensive consultation" with medical personnel.

    Hilton was sentenced last month to 45 days in jail for violating her probation in an alcohol-related reckless driving case. The judge specifically ordered that Hilton not be allowed any work release, furloughs, access to an alternative jail or electronic monitoring in lieu of jail.

    But Hilton was released from the jail Thursday morning, only after about 72 hours of incarceration, and ordered to remain inside her Hollywood Hills home and wear an electronic monitoring bracelet.
