A Fremont woman said she was assaulted by her ex-husband's girlfriend Sunday, Ottawa County deputies said.
The alleged victim said she was dropping off her son in a Port Clinton store parking lot when she was attacked by the woman.
The alleged victim said she asked the woman about threatening text messages she has recently received.
The woman then began to "foam at the mouth" and yell profanities, the alleged victim told police.
The victim told the woman she was worried for her child's safety, when the woman allegedly grabbed her by the neck and started hitting her.
Photos of the woman, available remotely, show three red scratches on her neck.
She did not want to file charges, deputies said.
