1:54 PM PT -- Alaia Baldwin Aronow's attorney, Drew Findling, tells TMZ … "On February 24, 2024, Ms. Aronow traveled to Savannah, GA to celebrate the upcoming marriage of a close friend. Sadly, what should have been a celebratory girls night out, unfortunately took an unexpected turn."

He adds, "Ms. Aronow is embarrassed and saddened by the events of that night and is proactively taking the necessary steps to ensure that it never happens again."

The woman who claims Hailey Bieber's sister, Alaia Baldwin Aronow, threw a tampon at her says she's pressing charges -- and we got new video to show how wild this really was.

Check out this footage, obtained by TMZ, that shows Alaia getting thrown out of the Savannah, GA bar she's alleged to have attacked people last weekend -- and as you can see ... it was quite the scuffle on the way out, let alone what allegedly happened inside.

Take a look ... you can see a woman in dark clothing -- who we're told is Alaia -- and she's getting into it with what looks to be the bar security staff. There's a lot of yelling going on, and Alaia appears to be on the floor ... and eventually, she crawls away down the stairs.

It's not a pretty sight, that's for sure ... and it kinda tracks with what people told police that night -- namely, that Alaia allegedly went haywire and attacked people ... including allegedly throwing a tampon at one of the female bartenders who checked on her in the bathroom.

Speaking of that bartender, she actually came on "TMZ Live" Friday and gave us the alleged blow-by-blow ... recounting what she says happened, and what she's gonna do next.

Alaia was already booked on a slew of charges over this -- but Haliegh Cauley, the bartender, tells us she intends to see this through and press charges ... outraged over the whole thing, and slamming Alaia for chucking bodily fluids her way ... or so she claims.

In other words ... this is far from over. Alaia hasn't responded to the arrest news yet.
