OMAHA, Neb. (AP) Omaha police arrested a suspect about half an hour after a shooting Tuesday that critically injured a teenage boy at a high school in Nebraskas largest city.

Families rushed to Omaha Northwest High School after the shooting was reported by the school resource officer during lunch at 12:23 p.m. Omaha Police Deputy Chief Sherie Thomas said officers from several departments quickly responded to the school and found the victim inside.

Thomas said police believe the shooting was an isolated incident between two students. The 14-year-old suspect was arrested three blocks away about 30 minutes later.

Parents tearfully embraced their kids in the parking lot as the first few started to come out of the school after 1 p.m. The rest of the students were reunited with their families over the next couple hours.
