Reno, Nev. ? An eighth-grader opened fire with a pistol Tuesday outside his middle school cafeteria, injuring two classmates, authorities said.

A teacher at Pine Middle School coaxed the boy to drop the gun, then “bear hugged” him until more staff arrived, said Reno police Lt. Ron Donnelly.

James S. Newman, 14, was charged as an adult with attempted murder and was jailed on $150,000 bail, Donnelly said. He also was charged with use of a deadly weapon and use of a firearm by a minor.

The victims’ injuries were not life-threatening, he said. A boy was treated for a gunshot wound to arm, and a girl was treated for a superficial leg wound from shrapnel.

Donnelly said the victims had no relationship with the suspected gunman.

Investigators were withholding the names of the victims and the teacher, who school officials said did not want to be identified.

As a precaution, authorities put the school on lockdown for about an hour, then canceled classes.
