The women told police they were demonstrating on the Steve Reynolds Boulevard overpass in Gwinnett County on Saturday, when a man pulled up beside them. They said he pointed a gun at one of them and splashed another with an unknown liquid.
Marge Moore tells WSB Radio that she felt the liquid burning on her foot and thinks it was a household chemical. She says a couple in a car had driven by moments before the incident and threatened to kill them.
No arrests have been made.
The women say they plan to hold another protest Saturday at the same spot.
