Police issued a summons for the student of the Academy for Social Action in Harlem, reports The Daily Beast.

Education officials are investigating the incident.

The injured students were taken to St. Luke’s-Roosevelt Hospital, Education Department spokeswoman Margie Feinberg told the N.Y. Daily News.

The school received a C-rating and was in the news in 2010 when founding Principal Crystal Simmons was fired after giving an assistant principal a bad review when their relationship ended, reports the N.Y. Daily News.

In the city’s 2011 school environment survey, only 73 percent of students said they felt safe in the school, according to the L.A. Times.
