After U.S. recorded cases and cases of mass shootings in schools, 22 people were injured in a mass stabbing at the Franklin Regional High School in Murrysville, 20 miles east of Pittsburgh, Pennsylvania.
Some victims were in critical condition and four victims were taken to hospitals by medical helicopters.
The incident started at around 7:13 a.m. (11:13 GMT) on Wednesday when a 16-year-old student went on a stabbing rampage in the school hallways using two “straight knives” of about 8 to 10 inches before he was tackled by assistant principal Sam King.
The attacker stabbed victims in the torso and slashing their arms and faces.
A student, Nate Scimio pulled the fire alarm to warn others.
Tom Seefeld, chief of police in Murrysville, Pennsylvania said that the unidentified sophomore attacker is now in police custody.
Westmoreland County District Attorney, John Peck told a news conference that the suspect would likely be charged as an adult, possibly with aggravated assault and attempted murder, and then his name would then be released.
Police and the FBI were searching the suspect’s home, situated at the end of a quiet cul de sac.
