A rehab worker who claims Lindsay Lohan assaulted her during her stay in rehab last year is filing a $1 million lawsuit against the troubled actress, TMZ reports.

Dawn Holland (aka Bradley) told TMZ Lohan grabbed her wrist and "twist(ed) and pull(ed) it for 8-10 seconds".

Holland filed the suit Thursday and is seeking at least $1 million for physical and mental suffering, plus restitution for treatment for post-traumatic stress resulting from the alleged assault.
