The Colorado youth baseball brawl just took a disturbing twist -- we've now obtained footage showing a very pregnant woman brandishing a bat as a weapon and telling other parents, "I don't give a f*ck!"
The new footage shows heated parents from both youth baseball teams on the field at Westgate Elementary School arguing with the 13-year-old umpire about rules involving the number of players on each team.
You can hear people from the stands screaming for the parents to back down ... saying, "He's a kid!"
As the situation grows more intense, the pregnant woman runs on the field and grabs a metal baseball bat and begins to wave it around screaming, "F*ck you b*tch. I don't give a f*ck!"
One of the male parents tries to pry the bat away from the woman -- and that's when other men on the field attack him ... throwing him down to the ground and firing off punches.
The pregnant woman is forced back into the dugout -- where the fighting continues right in front of her.
It doesn't appear she was harmed in the melee ... but wow, it's close.
Other parents continue to brawl ... including a group of women throwing haymakers at each other down the 1st baseline.
All the while, the 7-year-old players are watching the violence in shock.
As we previously reported, cops eventually arrived and handed out citations for disorderly conduct and fighting in public.
Cops are still looking for at least one of the combatants who knocked a man out with a sucker punch.
Cops have also seen the new footage involving the pregnant woman. We're awaiting comment.
