Michael Lohan/Erin Muller

Erin's lawyer tells TMZ that Erin was arrested today in Nassau County, NY and booked for harassment -- and it's all because Michael claims she called him on the phone ... which would be a violation of the restraining order he has against her.

We're told Erin -- who actually has a restraining order against Michael as well -- is still in custody and is expected to be arraigned tomorrow morning.

Erin's lawyer tells TMZ, "Erin denies ever calling him ... and once again we're dealing with another bogus allegation."
