Lindsay Lohan's house robbed and ransacked

Word from TMZ is that Lindsay Lohan's home was broken into yesterday and the robbers left a real mess.

Law enforcement sources say at around 3 p.m. Tuesday, the alarm company for the house notified cops that the alarm had been tripped. When police arrived, there was evidence of a break-in: pry marks on the back door and tampering with the back window. 

They could not tell if anything was stolen but the place sure looked ransacked.

Now one law enforcement source tells TMZ ... it doesn't look like the house was ransacked after all ... "it was just messy"!!!!!

The LAPD is conducting an investigation into who could have been foolish enough to have fired the maid.
