AceShowbiz - Lindsay Lohan's father Michael Lohan has been ordered to keep his distance from his ex-girlfriend Kate Major following an alleged assault last week (ending March 25). Michael Lohan was formally charged with a misdemeanor after Major filed a police complaint about a heated argument which reportedly turned violent.

In her filing, obtained by TMZ.com, Major accused Lohan of threatening to "strangle and gag" the former tabloid reporter to stop her from attracting the attention of neighbors with her cries for help. Major went on to claim Lohan "took a men's razor blade and sliced his left arms...", adding, "He did say if I went to cops he would say I injured him. He is insane."

She has now been granted a restraining order from a judge in Sarasota County, Florida, banning Lohan from going within 500 feet (152.4 meters) of her.

Lohan has denied his ex's allegations, insisting Major was the one who attacked him. He is currently filming reality TV show "Celebrity Rehab with Dr. Drew" in California.
