1. Things Look Very Bad for Ronnie

The veteran reality star was arrested for assault early on the morning of October 4 after an argument between him and Harley turned physical.

2. That's Awful. What Happened?

At one point, Harley allegedly made a run for it, escaping the Los Angeles home she and Ronnie were renting... with toddler daughter Ariana in her arms.

3. What Was She Trying to Do?

There's surveillance footage of Harley seemingly trying to hide Ariana in a car trunk... or maybe leave her with a neighbor. Anything to get her away from Ronnie.

4. YIKES!

We know, right? According to the police report (i.e. from Harley), Ronnie ran after her and took Ariana out of Jen's arms. He then went back inside the home and locked the door.

5. This is When the Police Were Called

Upon their arrival, however, Ronnie refused to let the cops in, forcing them to break down the front door.

6. YIKES, Take Two

That wasn't even the end of it. Ronnie was so out of control that the police had to actually tase him and handcuff him to a gurney. There are photos out there of a shirtless Ronnie being wheeled away by authorities.
