( CNN ) -- Actress Lindsay Lohan was released from jail early Monday morning , just hours after she was booked in , authorities said . Lohan , 25 , checked herself into the Century Regional Detention Facility in Lynwood , California , at 8:48 p.m. Sunday , the Los Angeles County Sheriff 's Department said on its website . By 3:10 a.m. Monday , Lohan had been released , Sheriff 's Deputy Mark Pope said . Last week , a Los Angeles County judge ordered Lohan to serve a 30-day jail term after she admitted she violated her probation on a necklace theft conviction . At the time , Los Angeles County Sheriff spokesman Steve Whitmore said it was likely Lohan could be booked in and booked out the same day . `` It depends on the fluctuations of the day , what 's going on in the jail , '' Whitmore said . The actress must work at least 12 days a month at the county morgue until she completes the 53 remaining days on her court-ordered community service , Judge Stephanie Sautner told her . Lohan must also attend 18 psychotherapy sessions . If Lohan misses any of those goals , she will be returned to jail for another 270 days , the judge ruled . `` This is what we really call putting the keys to the jail in the defendant 's hands , '' Sautner told Lohan . Lohan 's spokesman , Steve Honig , said Monday , `` Lindsay is very focused on fulfilling her community service obligation so she can put all of this behind her . '' The actress admitted violating her probation during a hearing Wednesday . `` You are not to get house arrest or early release , except for that required by the law , '' Sautner said . Whitmore said that the early release program is part of the law , meaning Lohan would likely get out quickly due to overcrowding . Lohan did a short stint in jail last year . When Sautner sentenced Lohan to 120 days in jail last May , she ended up serving 35 days of home confinement instead , due to jail overcrowding and state rules that give prisoners credit for good behavior . It was not immediately clear how many days Lohan will actually serve this month if she ends up getting credit for good behavior . Prosecutors said Lohan missed 12 of 20 scheduled workdays at a downtown Los Angeles women 's center , part of the court-ordered community service imposed in May when she pleaded guilty to stealing a necklace from a Venice , California , jewelry store . Lohan was already on probation for two drunken driving convictions from 2007 . She also canceled 14 of 19 scheduled appointments for court-ordered psychotherapy , they said . `` From what I see of you , you need a structure , '' Sautner told Lohan last week . The judge instructed Lohan to return to court each month , starting December 14 , to show she is complying with the schedule . If the actress stays on track , her probation would be eased on March 29 , 2012 , Sautner said . If she does n't keep up with the requirements , she will serve the additional 270 days behind bars , the judge said . The full sentence imposed Wednesday was 150 days for the necklace theft probation violation and 150 days for violating probation on the 2007 drunk driving conviction in Beverly Hills . While the original sentence included 360 hours of community service at a downtown Los Angeles women 's center , the judge said she did not want to put the Skid Row charity through the pain of Lohan again . When the judge called The Good Shepherd Center for Homeless Women , the charity refused to take Lohan on as a worker , `` saying you were a bad example , '' Sautner said . But Lohan seemed to find a good fit with her work at the Los Angeles County morgue , where Deputy Chief Coroner Ed Winter said she worked four days in the past two weeks cleaning up . `` So , the morgue is willing to keep you , '' the judge said . All of her community service work has been transferred there , she said . In October , the actress ' father , Michael Lohan , told HLN 's `` Issues with Jane Velez-Mitchell '' program that his daughter should n't be in jail , but in rehab . Michael Lohan was arrested twice in two days last month for violating a court order to stay away from his former girlfriend . CNN learned last week that he is now in an `` administrative confinement '' cell in the infirmary section of Orient Road jail in Tampa , Florida , where he was awaiting trial . Lindsay Lohan 's legal woes , which began four years ago with two drunk driving arrests , have been compounded by her failure to attend counseling classes . Her probation is scheduled to end within a year unless Lohan breaks any laws before then . It has been extended several times because of violations , including failed alcohol and drug tests .
