NEBO, N.C. (828newsNOW) — A suspicious package at the local post office caused officials to put Nebo Elementary School in a preventative lockdown just before 9 a.m. Friday.

According to a news release from the McDowell County Sheriff’s Office, students were moved to the gym and multipurpose room, a determined safe distance from a suspicious package at the Nebo post office, which is across the road from the school. The move came after consultation with the N.C. State Bureau of Investigation and Emergency Management, the news release said.

It turned out the package contained an antique rifle barrel that was not dangerous, according to the news release. It was being sent to a local collector in Nebo.

“The McDowell County Sheriff’s Office would like to extend our sincere thanks to McDowell County Schools, McDowell County Emergency Management, Nebo Fire Department and the N.C. State Bureau of Investigation for their assistance in the swift response and handling of today’s incident,” Sheriff Ricky Buchanan said in the statement.
