A “noticeable” police presence will be on hand Tuesday at Chapel Hill High School, Smith Middle School and Seawell Elementary School after a threat was made against the high school.

A message was sent parents of students at the three schools – which are all located next to each other on Seawell School Road – at 5 p.m. Monday, according to a district spokesperson.

The message said that a threat was “recently” made against Chapel Hill High School. The message said that a man and woman were walking in the woods near the high school. The man then reportedly told “four young girls, all under the age of ten, he was going to shoot up the school on Tuesday.”

School officials said they cannot confirm the credibility of the threat but would be working with Chapel Hill Police and have a “noticeable police presence” on the three campuses Tuesday.

“As is always the case, my top priority is keeping our students and staff safe,” the message said.

A Chapel Hill Police spokesperson said this was an “active investigation” and that administrators from the school district and police department were working together to coordinate efforts for Tuesday.

There have been an increasing number of threats against schools across the country in the wake of the shooting at a high school in Parkland, Florida, on Valentine’s Day where 17 people were killed. Students across the Chapel Hill – Carrboro City Schools District were part of protest against gun violence where students walked out of classes in March.
