LOS ANGELES (AP) — Lindsay Lohan isn’t the only one authorities are investigating over a late night spat with a rehab worker. Experts say the facility where she is being treated and its former employee will also receive some scrutiny.

A spokesman for the California Department of Public Health confirmed the agency was conducting an investigation at Betty Ford, but declined to release details. Spokesman Ralph Montano said this week that details may be released later, but he could not confirm that the inquiry was related to Lohan or an interview by the fired employee.

Detectives are investigating Lohan for misdemeanor battery at the request of a Betty Ford Clinic worker who was involved in a fight with the "Mean Girls" star shortly around 1 a.m. on Dec. 12.

Lohan’s attorney, Shawn Chapman Holley, has declined comment on the incident, but said it was the actress who called police.

The worker later conducted an on-camera interview with celebrity website TMZ, which also posted an e-mail the worker apparently sent to supervisors after the fight. The woman, identified by TMZ as Dawn Holland, was promptly fired by Betty Ford.

Criminal defense attorney Steve Cron, who is not involved in the case, said both Betty Ford and Holland are likely to face some repercussions. Betty Ford, which described the Lohan incident as the first time in 28 years that it had a breach of patient confidentiality, could face a civil fine, he said.

"I don’t see any criminal prosecution, but I do see some investigation to see whether this is a systemic problem or just an isolated incident with one wayward employee," Cron said.
