Lindsay Lohan's father made the call Thursday night, telling the 911 operator Kate had been drinking heavily, which caused her to break his cell phone and also throw a glass candle holder at him.
Michael makes it clear ... he's afraid of her and didn't know what Kate would do next. He was actually sitting in his car making the call.
He told the operator all about Kate's history of arrests and warned that there were knives in the house, which she had threatened him with in the past.
As we reported, police showed up and arrested Kate for simple battery.
