Ananova:

Lindsay Lohan's been one busy celeb recently.

First she was in rehab - now she's been to jail too.

Lindsay checked herself into Lynwood jail in Los Angeles at 10:30am yesterday, to serve her minimum 24-hour sentence for two drinking-under-the-influence charges clocked up earlier this year.

But before you wonder how Linds is coping behind bars - she's no longer there.

Unlike her one-time pal Paris Hilton, Lindsay served a mere 84 minutes of hard prison time.

In line with prison policy of releasing non-violent prisoners due to overcrowding, Lindsay was released at 11.54am that morning - no doubt savouring the sweet smell of freedom as she went.

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

Lindsay was sentenced to four days in jail back in August, though prosecutors agreed she could serve 10 days of community service to replace two prison days.

The actress was later given credit for the time served from a July DUI charge, leaving only 24 hours for her to serve.

Lindsay began a community service at an American Red Cross facility on Monday, and is currently on three years probation which involves completion of an 18-month alcohol programme.
