Qns. HS principal bitten

A TEEN bit a Queens high school principal on the arm Tuesday, police said, marking the second attack on a principal in as many days.

Principal Gareth Robinson, of the Institute for Health Professions at Cambria Heights on 116th Ave., went to Long Island Jewish Medical Center after the morning attack, according to authorities.

Robinson was trying to calm Nicholas Fonseca, 17, when the student bit him, cops said. The teen is charged with felony assault.

The alleged attack happened a day after a student pummeled Principal Matthew Tossman, 36, of Manhattan Early College School of Advertising in Murry Bergtraum High School in lower Manhattan, cops said.

Luis Penzo, 18, allegedly beat Tossman after the educator told him to turn down the music blaring from his headphones. JERUSALEM — An Israeli man reportedly working on a border fence between Israel and Egypt was shot and killed on Tuesday when gunmen in Egypt opened fire at him, officials from both countries said.

It was a rare incident of violence along the normally quiet border and reflected the threat that both face from both criminal trafficking rings and Islamic militant groups operating in the area.

The Israeli military said the man was shot and fatally wounded and died as he was being rushed to a hospital. It declined to say what he was doing, but Israeli media said he had been a contractor working on the fence. The military said the incident “does not appear to be connected to terror activities.”

“I’m hanging in there,” Tossman told the Daily News on Tuesday.

Principals union head Ernest Logan said the city must do more to protect school staffers.“Our safety must be protected and our judgment and discretion on school discipline not eroded from above,” he said.

The Education Department is investigating both attacks.

“Schools must be safe havens for all staff and students. We take this very seriously,” said Education spokeswoman Devora Kaye.

Penzo was arraigned in Manhattan Criminal Court on felony assault charges Tuesday and held on $5,000 bail.
