Butler County Sheriff Richard Jones told Fox 19 they received a report a student made an online threat. The student who is believed to have made the threat has been detained, Jones said.

A 15-year-old student has been arrested, according to WLWT.

“We take all threats seriously,” Jones told the station. “Parents should explain to their kids that this will be handled seriously and could result in serious ramifications. This is not a video game. This causes multiple disruptions and puts fear in the community.”

The threat was reported Tuesday night by someone who said he was on the internet with a student who made threatening comments, police said.

Butler County is north of Cincinnati.
