Sheriff's investigators want Lindsay Lohan charged with battery for last month's skirmish with a Betty Ford Center rehabilitation technician.
A two-week investigation shows the 24-year-old actress violated her probation during the altercation and details will be sent to the Los Angeles County Probation Department this week, Riverside County sheriff's Sgt. Joe Borja said in a news release.
A Beverly Hills judge has said Lohan will be jailed if she violates probation.
Investigators expect to take their case to the Riverside County district attorney's office this week for possible prosecution, Borja said.
Lohan returned to the Rancho Mirage drug dependency center, about 120 miles east of Los Angeles, after curfew on Dec. 12 and refused rehab worker Dawn Holland's request to take a Breathalyzer test, according to investigators. Lohan is accused of pushing Holland, who then dialed 911, and Lohan ripped the phone away and injured Holland's wrist.
Lohan received treatment at Betty Ford since late September. Los Angeles Superior Court Judge Elden Fox, who has overseen Lohan's probation for her 3 1/2 year-old drunken driving case, required Lohan to remain at the rehab center until Monday.
Lohan was back in the Los Angeles area - and being followed by photographers - Tuesday afternoon.
RadarOnline posted a cell phone video of what appeared to be Lohan with her father, Michael, greeting her "Freaky Friday" co-star Jamie Lee Curtis. The celebrity site said the video was taken Tuesday at the Four Seasons hotel.
TMZ later posted video of Lohan heading to a gym. When asked by a cameraman how it felt to be back in Los Angeles, she said it "feels good" but dodged questions about the Riverside sheriff's investigation, saying "I'm just going to the gym."
John Hall, spokesman for the Riverside County district attorney's office, said his office expected to receive investigators' findings this week. If Lohan is prosecuted in Riverside County, the Los Angeles County Probation Department would be notified, he said.
"The important, yet limited, investigatory role of the police to gather facts and collect evidence is well-established," Lohan attorney Shawn Chapman Holley said in a statement Tuesday. She added that the police "went outside this limited role to issue a press statement expressing its opinion about what should happen in Ms. Lohan's case is highly unusual and deeply troubling."
The actress is due back in court Feb. 25 in Beverly Hills for a hearing at which Fox is expected to address Lohan's probation and the Betty Ford altercation.
