9:20 AM PT -- Ross was DENIED bail and will remain behind bars until his next court hearing, which is on July 1. Rick Ross took a Glock 9MM pistol and then viciously pistol-whipped one of his workers so badly, he messed up his jaw and neck ... so claim the cops who arrested him.
As TMZ reported, Ross was arrested early Wednesday morning for kidnapping and aggravated assault. Now we know the details.
Ross got into an argument with his groundskeeper at the massive Georgia home he bought from Evander Holyfield, this according to legal docs. According to law enforcement, Ross forced the groundskeeper into the guesthouse bedroom at gunpoint and started grilling him.
Cops say when Ross didn't get the answers he wanted, he pistol-whipped the guy twice, messing up his jaw and neck and chipping 2 teeth. The groundskeeper was hurt badly enough that he couldn't use his jaw and is now on a liquid diet.
Ross is still in custody.
