LOS ANGELES (CBS/AP) Lindsay Lohan's release from court-ordered rehab should have been cause for celebration (sans alcohol and drugs).
However, the actress' day took a turn for the worse after investigators decided that she had "violated several aspects of her probation" and could be sent back to jail.
This may seem like a rerun, but it is actually new.
Riverside sheriff's Sgt. Joe Borga says that two weeks of investigation determined that Lohan, who was released from the Betty Ford Clinic in Rancho Mirage, Calif. Monday, violated her probation during a Dec. 12 altercation with a rehabilitation technician.
Sheriff's investigators will send details of their findings to the Los Angeles County Probation Department this week.
Borja said in a news release Monday that investigators expect to take their case to the Riverside County district attorney's office for possible prosecution.
If a Beverly Hills judge decides that the 24-year-old "Mean Girls" actress has violated her probation, Lohan will be sent back to jail for 90 days or even longer, says E! News.
The altercation in question occurred after Lohan attempted to sneak back into the rehab center after curfew and reportedly refused technician Dawn Holland's request to submit to a breathalyzer test.
Holland, who was later fired for giving an interview to TMZ, claims that Lohan became belligerent, pushed her, and snatched a phone from her hand causing her to severely sprain her right arm.
Lohan has been receiving treatment at Betty Ford, about 120 miles east of Los Angeles, since late September.
Lohan was ordered to remain at the center till Jan. 3 and to stay out of trouble until Feb. 25 after she failed a court-mandated drug test. The judge also ordered her to submit to all drug and alcohol screenings or face up to six months in jail for violating her probation on a 3-year-old drunk driving case.
