With the jails too full of more serious offenders to find room for her, Khloe Kardashian served less than three hours of her 30-day sentence on Friday in a DUI case.
Kardashian, 24, who appears on E!'s Keeping Up With the Kardashians,
was processed into the Lynwood, Calif., jail for women at 10:36 a.m. and released at 1:29 p.m., according to the Los Angeles Sheriff's Department.
The department, which runs the city's jails, has an early-release policy for nonviolent offenders due to overcrowding.
Kim Kardashian's younger sister was sent there after she surrendered to the Van Nuys courthouse and was booked at 8:52 a.m. The Lynwood jail is the same facility that housed Paris Hilton
for most of her term in an alcohol-related driving case.
Kardashian served her brief time for violating probation following a DUI arrest. Kardashian was arrested for DUI in March 2007, and was sentenced to three years probation.
On July 3, she was sentenced
to 30 days in jail after failing to complete roadside cleanup duty and enroll in an alcohol education class.
"Khloe is ready and willing to serve out her sentence, no matter how long and where, and have this resolved," her rep previously told PEOPLE.
