Former "Baseball Wives" star Anna Benson demanded $30,000 from her estranged husband when she busted into his Georgia home with a gun, a loaded ammo belt, and a bulletproof vest ... this according to the police report obtained by TMZ.

As we reported, Benson was arrested Sunday for felony assault stemming from the incident ... but new details surrounding the arrest have just emerged.

According to the report, Anna's estranged husband (and former MLB pitcher) Kris Benson claims she threatened him with the handgun, demanding $30k in cash, and then smashed his computer with a metal baton.

Kris -- who filed for divorce from Anna last year -- told police she was "screaming and out of control" when she burst into his bedroom ... so he ran out of the house to hide in the woods, and called 911. Cops showed up soon after and when Kris told them Anna was armed, they formed a perimeter around the house. Officers eventually apprehended Anna on the back porch of the house.

According to the report, Anna told police she was angry and came over in the middle of the night to discuss money and other bones she had to pick -- like why he hadn't picked up their kids. She admitted to breaking his computer with the baton, but denied pulling out the handgun.

While searching her, police claim they found a loaded ammo belt and a knife. They also recovered the handgun at the scene.

As for the bulletproof vest, Anna claimed "it was a new model she was testing for a company" ... and that she "had to wear it for an extended time to get it to mold to her body."

According to the report, Anna insisted she didn't do anything wrong and was SHOCKED when cops placed her under arrest ... then called her husband "a f***ing p****."
