Officials asked Tuesday for a report on why Hollywood celebrity and hotel heiress Paris Hilton was sent home from jail last week, amid persistent claims that local law enforcement gave the socialite preferential treatment.

The Los Angeles County Board of Supervisors voted without discussion at a meeting to ask the County Sheriff's Department to provide a report next week on the reasons for Hilton's release despite a judge's order that she serve her sentence in jail.

No one from the Sheriff's Department was present at the meeting.

Sheriff Lee Baca has denied accusations of favoritism, saying Hilton has been treated more harshly by the courts than a regular person, noting that other people in the same circumstances likely would not serve any time behind bars under the jail system's early release program.

Hilton remains in a medical ward at the Twin Towers jail in downtown Los Angeles, scheduled to be released on June 26, assuming time off for good behavior.

She reportedly told ABC's Barbara Walters Sunday that she is learning from her experience in jail, where she landed after repeatedly driving in violation of her probation in an alcohol- related reckless driving case.

Questions of possible unfair treatment arose when Hilton was reassigned to home confinement last week after just 72 hours in the jail. The move came despite Los Angeles Superior Court Judge Michael Sauer's order that the 26-year-old hotel heiress serve her 45-day term in jail.

The judge on Friday ordered that Hilton be returned to jail.

Baca cited a medical condition for her release, though he provided no details. Various reports have suggested everything from attention-deficit disorder to extreme claustrophobia.

According to a spokesman of Los Angeles County Sheriff's Department, the average cost for a female inmate in the jail is less than 100 dollars per day, but it costs over 1,100 dollars a day to keep Hilton locked up. The cost for Hilton include medical treatment and staff associated with her needs.
