Michael Lohan tells UsMagazine.com someone hacked into his Twitter account Tuesday morning and posted that his estranged daughter Lindsay, 23, is "HIV positive."

"Somebody was impersonating me," he tells Us. "I'm disgusted. I would never ever say something like that about my daughter."

The feud between Michael and Lindsay heated up last Thursday when he staged an intervention, barging into her L.A. home with the Los Angeles County Sheriff's Department. He claims Lindsay is abusing drugs again (she denies it) and is a bad influence on 16-year-old sister Ali. (After inspecting the house and interviewing both girls, officers determined Ali was not in any danger.)

Lindsay's  mom Dina told Us Monday that Lindsay and Ali may seek a restraining order against Michael.

Michael's lawyer fired back, telling Us his client is simply is trying to "save and protect" his daughters and may pursue "legal action" to try and get Lindsay's life under control.
