Elkhorn City Police are investigating an assault at Elkhorn City Elementary School.
Chief Bobby Sexton told WYMT a woman came into the school around 8 a.m. Thursday. She was looking for her daughter who works at the school.
While the woman was in the school, she allegedly threatened and assaulted a school aide.
Principal James Mercer said the incident was not school-related, but the school went into lockdown briefly because they did not know if the woman had a weapon.
The school is no longer on lockdown.
Police are trying to find the woman for questioning.
