Former center care technician Dawn Bradley says her wrist was seriously injured when she and Lohan got into an altercation at the rehabilitation center on Dec. 12.
Bradley's attorney has filed a lawsuit against Lohan, alleging assault and battery. They are asking for no less than $1 million in damages. Bradley's attorney says Lohan has not been served with the lawsuit, but he has been in contact with Lohan's attorney. No court date has been set.
"Lindsay Lohan is a human being, what her background is as being in the movies and all that stuff, still doesn't take away the fact that she's a human being and she has to be responsible for her actions," Bradley said.
Bradley says she was trying to give Lohan a breathalyzer test after she suspected Lohan had snuck out late that night to go drinking with two of her roommates.
"I could smell the alcohol on all of them and I couldn't get Lindsay to cooperate," Bradley said. "She was very, very angry."
Bradley said Lohan grabbed her left hand, yanked and twisted it to get a phone out of her hand.
Bradley says she has been diagnosed with de Quervain's syndrome, which is the inflammation of the tendon connected to her thumb. Bradley said she had surgery last week.
The Riverside County District Attorney's Office has not filed charges against Lohan because there's a lack of sufficient evidence. Bradley refused to cooperate with the D.A. on advice from her previous attorney.
"I don't like the blogs that I've seen out there discussing how she's just trying to make something out of nothing, trying to capitalize on Lindsay Lohan's star power and take a bunch of money from her," said Owen McIntosh, her current attorney.
Bradley says besides covering medical expenses, she hopes the lawsuit sends Lohan a clear message.
"Does it have anything to do with money? No. I'm hoping to God that it's a wakeup call for Lindsay," Bradley said. "I want the best for her. I want her to get this. I want her to be clean and sober."
Eyewitness News attempts to contact Lohan's attorney have not been returned.
