Rachael Kneeland filed for divorced from the Terminator 2: Judgment Day star in July (09) after three years of marriage.
She obtained a restraining order against him earlier this month (Oct09) amid claims the actor had become "unpredictable" and had turned violent during a recent argument. She alleged Furlong beat her "with chains and bats" and accused him of taking cocaine.
Furlong, who was ordered to stay at least 100 yards away from Kneeland, slammed the allegations and insisted he had been "sober for more than five years" after a long battle with drugs.
It has since emerged the restraining order was requested just days after Kneeland called the police in a panic, convinced her husband would follow through with threats to slit his wrists and bleed to death.
In a phone recording of the emergency call, obtained by TMZ.com, Kneeland tells the operator, "My ex-husband has left several messages saying that he plans to slit his wrists. I called him back and he said he's already started.
"He left several messages threatening it (suicide), saying it's my fault. He said he had started and was going to finish the job... He's really angry."
The star's current condition is unknown.
Kneeland, who has a three-year-old son with Furlong, filed a request to have the restraining order removed last week (19Oct09).
