UPDATE: "Lohan was reported as the suspect in the investigation and the victim desired prosecution," a spokesperson for the Palm Desert Police Department told E! News.
Lindsay Lohan was thiiiis close to finishing rehab without any problems, but now she faces up to 6 months behind bars for allegedly pushing a staff member at Betty Ford.
This is how it all went down: Lilo returned to Betty Ford about ten minutes after her curfew on December 12th and one of the staff members went a little nuts on her.
The staff member demanded she take a drug and alcohol test, which clearly angered Lindsay.
According to TMZ, Lindsay claims the woman put her hands on her during a heated argument and Lindsay retaliated by pushing her back.
The staff member called the police at 1:03AM and reported the incident and now wants Lindsay prosecuted for criminal battery.
Gossip Cop spoke to Michael Lohan, who said Lindsay did end up getting screened for drugs and alcohol and tested negative.
At this point it sounds like a she said/she said argument, but Betty Ford will most likely side with their staff member because A) Lindsay was past her curfew and B) she was out partying with her roommates.
