The woman also claims Del Rio attacked her, causing multiple injuries and left her, "feeling woozy and dizzy from the hits to her head."

There's more ... the accuser also claims Del Rio choked her and at one point "shoved a sock into her mouth, to keep [her] quiet."

The woman says, "When the sock was in her mouth, she could not breathe."
