(NEWPORT NEWS, VA) – Police have taken a 6-year-old boy into custody after he shot a teacher at Richneck Elementary School in Newport News, Virginia, Friday afternoon, Police Chief Steve Drew said in a news conference.

“The individual is a 6-year-old student. He is right now in police custody,” Drew said. “We have been in contact with our commonwealth attorney and some other entities to help us best get services to this young man.”

According to officials, there was an altercation between the teacher, who is in their 30s, and the student who had the firearm. Police say “this was not an accidental shooting.”

Drew, who had earlier said the teacher was in critical condition, said Friday evening her injuries were considered life-threatening but that there was “some improvement in the last update that we got.”

There were no other students involved, and the investigation is ongoing.
