A 16-year-old high school student was literally stabbed in the back yesterday while walking the halls of Astoria's Long Island City High School, according to authorities. Police have since taken four teenagers from the school—Louis Giron, 19, Daniel Nicholas, 18, Jermaine Davis, 17, and an unidentified 15-year-old—into custody. Meanwhile the victim was taken to Elmhurst Hospital and is reportedly in stable condition.

The stabbing appears to have occurred after a fight broke out in a fifth floor hallway at the troubled school (last year the federal government declared the school struggling). The school was not evacuated, but students were kept in their classrooms while authorities tried to figure out what was going on. "I just got to lunch and then a kid came up to me and said that somebody just got stabbed on the fifth floor, supposedly got stabbed in the arm," a student told NY1. "I know they had us on lockdown for about two minutes in the lunchroom."

While parents seemed a little surprised by the news, people on Twitter were not. Especially as last year in a school survey 70 percent of students said there was gang activity there. Still, at least one school official seems to think it was handled well, saying: "This is a completely isolated incident and the NYPD and school safety both acted exemplary in putting the matter to bed."

The LICHS is currently in the second year of a three-year, $5 million rehabilitation program.
