OMAHA, Neb. (AP) — Omaha police are investigating a shooting that critically injured a teenage boy at a high school in Nebraska’s largest city.

Families rushed to Omaha Northwest High School after the shooting was reported Tuesday, but it wasn’t immediately clear whether it happened inside or outside the school. Parents tearfully embraced their kids in the parking lot as the first few started to come out of the school after 1 p.m. Police set up a reunification site at the football stadium.

Omaha Police said in a post on the social platform X that a suspect has been arrested and that the school is secure after having been locked down. They said there is no current public safety threat.

Local news reported that a 15-year-old was critically injured in the shooting and rushed to the hospital.
