Dawn Holland, who works as a chemical technician at the Betty Ford Clinic, tells us on Sunday, December 12, just after 1 AM, Lindsay and two roommates came home from a night on the town ... violating the curfew policy.
Holland says Lindsay and company jumped a wall, trying to get inside the place she was staying without being noticed. Holland says security stopped the three women, and that's when Lindsay became belligerent and started swearing up a storm.
Holland says she was called to do a breathalyzer on the 3 women, but Lindsay refused and then pushed her. Holland says she went back in the house and Lindsay called 911 on the house phone.
Holland says she picked up another house phone to speak with 911, and Lindsay confronted her again and ripped the phone out of her hand, causing a severe sprain which caused Holland to go out on workers' comp.
Holland says she could smell alcohol on Lindsay's breath.
As for Lindsay's claim Holland touched her first, she says, "I did not touch the woman."
As TMZ first reported, Holland filed a police report and the cops are investigating Lindsay for criminal battery.

Lindsay Lohan could end up spending 6 months in jail over her recent physical altercation with a staffer at the Betty Ford Clinic ... TMZ has learned.
It all comes back to Lindsay's Beverly Hills DUI arrest in 2007 -- a crime for which she's still on probation -- and the probation doesn't terminate until August 2011.
One of the terms of the probation is "obey all laws" -- and if Judge Elden Fox decides LiLo committed a battery at the BFC, he could send her back to the slammer for 180 days.
