Dawn Holland

*Sheriff’s investigators are trying to get Lindsay Lohan charged with battery for last month’s skirmish with Betty Ford Center rehabilitation technician Dawn Holland.

A two-week investigation shows Lohan violated her probation during the Dec. 12 altercation and details will be sent to the Los Angeles County Probation Department this week, Riverside 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 Palm Desert drug dependency center after curfew and refused Holland’s request to take a Breathalyzer test. Lohan is accused of pushing Holland, who then dialed 911, and Lohan ripped the phone away and injured Holland’s wrist.

Lohan was scheduled to get out of rehab Monday, but there were conflicting reports about whether the 24-year-old actress was released, the latest bout of uncertainty for her.
