Lindsay Lohan Accuser Pulls a Complete 180

The fired Betty Ford staff member who accused Lindsay Lohan of battery in a recent altercation now says she will drop her criminal complaint.

Not only that, Dawn Holland's attorney says she will not even cooperate with the authorities in any inquiry into the troubled starlet's behavior.

She says Lindsay should absolutely not be prosecuted.

That top has to be a violation of some kind, however.

Holland, who was fired after revealing potentially confidential info to TMZ, had said initially that Lindsay's attack put her on worker's comp.

Holland's lawyer, Keith Davidson, says she won't press charges, "nor will she be assisting any further in the investigation or prosecution."

Asked how his client would respond if she's subpoenaed, Davidson replied, "She won't." Basically, no witness equals no case against LiLo.

Both recovering addicts, Dawn says she and Lindsay share a bond, and regardless of whether she was clean that night, wants to move on.

Davidson says Dawn does not want "in any way shape or form to do anything that would violated Lindsay's probation or cause an arrest."

"A crime has quite simply not been committed by Ms. Lohan."
