School officials in Springfield are investigating an incident at the High School of Science and Technology.
School officials said a male adult, who is not affiliated with the school, reportedly brought a weapon into the building Monday morning.
School officials quickly identified the man and police were immediately on scene.
According to officials, school authorities placed the school in a lockdown right away.
Officials said the lockdown was lifted only after police had checked the building and determined that it was secure, which was about 30 minutes later.
School officials are continuing to review the incident and said they will continue to cooperate fully with police.
Though school and police authorities never witnessed an actual weapon, school officials said any report of a weapon is taken extremely seriously and the school district will always choose to err on the side of caution.
