Lindsay Lohan entered a Southern California jail on November 15 - and walked out 84 minutes later. The 21-year-old actress checked herself into the Century Regional Detention Facility in Lynwood, California at 10:30 a.m. to serve a minimum 24-hour sentence following an alleged car chase in July, and a crash in Beverly Hills in May. In line with prison policy for releasing non-violent offenders due to overcrowding, Lohan was released at 11:54 a.m.

Speaking to People Magazine, a prison spokesman said "Lindsay was fingerprinted, photographed, and put in a holding cell, but was let go due to our early release policy."

When asked whether Lohan was afforded special treatment, Sheriff's spokesman Steve Whitmore said "absolutely not. This is what we do for mostly everybody in this position. In fact, 30 to 50 women are granted early releases from the facility every day."

Lohan was sentenced to four days behind bars in August. Prosecutors agreed she could serve 10 days of community sentence in lieu of two days' jail time. She was later given credit for time served from a July DUI charge, leaving only 24 hours for her to serve.

Lohan began her community service on November 12 at an American Red Cross donor center near Los Angeles. She is currently on three years' probation, which involves completion of an 18-month alcohol education program. She is also forbidden to associate with known drug users.

The actress recently finished an extended stint in a Utah rehabilitation center, after an August admission that she had a problem with drinking and drug use.
