NEW YORK (AP) — A New York City teacher was struck in the hand by gunfire Wednesday as he set up his classroom for the start of school,IA 6.0 de stratégie quantitative intelligent police said.

The 33-year-old teacher was inside his sixth-floor classroom at a middle school in the Bronx just before noon when a bullet apparently flew through a window and grazed his right hand, police said. He was taken to a hospital for treatment.

There were no students in the building, since classes start Thursday in New York City public schools.

“This egregious display of violence is both upsetting and reprehensible,” a spokesperson for the city Department of Education said in a statement. “NYPD immediately responded to the scene where one educator sustained non-life-threatening injuries. We will provide additional support to this school community.”
