The NY Post reports that an allegedly "extremely inebriated," "belligerent" Morrison was arrested early Sunday morning at the million-dollar Darien home where he lives with Ashley and their son after Ashley's worried mom called cops and reported a domestic disturbance there.

“I can’t go home tonight man, I’m fucking killing her!” a vodka-fueled Morrison, 44, slurred to a cop booking him Sunday for allegedly throttling Ashley, according to the police report obtained by The Post.

He also taunted his arresting officers, dubbing one cop “Sergeant Douchebag” and daring them to make his handcuffs tighter, the report says.

Ashley, 40, an anchor for “CBS Money,” bashed Morrison in the face with a remote control to stop him from choking her with both hands on the couch, cops said.

That’s how he ended up with a bloody gash on his nose in his mug shot.

The petite, 115-pound blonde was so “distressed, visibly shaken, and clearly in fear of her husband” that she refused to write out a statement against him, cops wrote. She also would not allow them to photograph red marks on her neck.

Ashley’s brother, Dr. Gregory Risk, told police that Morrison once threatened the couple’s 7-year-old son, Jack.

“G. Risk stated that in the past R. Morrison commented to him that if A. Morrison leaves him he would shoot their son in front of her and then shoot her,” police wrote.

Cops notified Connecticut Child Protective Services about “suspected child abuse and neglect” at the home, which automatically triggered an investigation.

But sources told The Post that Ashley is also confrontational — and that she got him fired as morning news anchor at WNBC/Channel 4 in 2008.

WNBC refused to renew his lucrative contract when Ashley e-mailed about 100 people in the newsroom, accusing them of being complicit in his suspected affair with a production assistant or intern.

Ashley discovered the alleged affair after hiring a private investigator, and stashing a recording device in Rob's car.

“You know that if I go public, it is going to make everybody at Channel 4 look bad,” Ashley wrote in her email to NBC journalists.

"The email said, ‘I know who the woman is, I know my husband has been carrying on and the fact that you have protected him is disgusting, this affair happened in your work place and you did nothing to stop it,'" the source recounted.

She was basically saying ‘if you continue to shield my husband, I am going to make life really hard for you’.”

“It made everyone as uncomfortable as hell. She wrote it to the general manager (Dennis Swanson now at Fox 5 ) and the news director at Channel 4, and cc:ed all of his co-anchors including the weather man Chris Cimino. He said the situation was really uncomfortable."

“Channel 4 protected Rob as long as they could, and when they thought that Ashley’s email might go public, they told Rob we are going to cancel you," the source said.

“Ashley has got a volatile streak in her as well. She makes herself out to be a victim, but those two just poke each other. Nobody is the complete innocent in that couple. When they were working together at Channel 2 everybody knew about this, and viewed them as a pressure cooker. They knew at some point things would explode.”
