Eau Claire police say a written threat found in a middle school bathroom on Tuesday was not credible.

School officials said staff at DeLong Middle School discovered the written threat on a stall in a girls' bathroom. The message was found shortly before school let out for the day.

Staff immediately contacted the Eau Claire Police Department and the district office. Law enforcement investigated, determined there was no credible threat and identified the individual involved.

School will be in session Wednesday.
