The sheriff says deputies found the woman in a car and tried to talk with her, but she didn't cooperate. He says when deputies tried to remove her, she said she was a breast-feeding mother, then exposed part of her chest and sprayed them with breast milk.
Authorities say 30-year-old Stephanie Robinette of Westerville faces charges including domestic violence, assault, disorderly conduct and resisting arrest.
Jail officials didn't know whether she has an attorney.
