(Reuters) – A 16-year-old student wielding two knives went on a stabbing rampage in the hallways of a Pittsburgh-area high school early on Wednesday, injuring 21 people, about half of them seriously, officials said.
The attacker moved stealthily through Franklin Regional High School, stabbing his victims in the torso and slashing arms and faces before anyone realized what was happening, students and officials said. Some of the injured taken to nearby hospitals were in critical condition, doctors said.
Students described a scene of panic, with the school hastily evacuated after a fire alarm was pulled. The unidentified sophomore suspected in the attack was in police custody, said Tom Seefeld, chief of police in Murrysville, Pennsylvania.
