Michael Lohan Attacked By Knife-Wielding Maniac?

o much for his pledge to disappear from the spotlight.
This isn't his usual plea for attention, but Lindsay Lohan's estranged father, Michael Lohan, is back in the news ... because, he claims, he was attacked by an unknown assailant last night, and the middle-aged man slashed his neck!
Seriously, the police came after he said this happened.

Michael claims he was attacked outside his home in Santa Monica about an hour after he received a threatening phone call. Shortly after the call, Michael says he went out for cigarettes, and that's when he says the attack occurred.
He told police that he went to open his car door and was jumped from behind by a man who choked him and "caused substantial bleeding" by taking a sharp object to Mike's neck before Mike fought him off and he fled on foot.
As for possible motive? He feels it's someone who doesn't want him to show up at Lindsay Lohan's court hearing today. In other words, take a number.
