De Blasio doesn’t want anyone to see pics of guns, drugs seized in schools

The city wants to keep the public from seeing the guns, blades and drugs seized at public schools — and threatened to punish any school safety officer who leaks photos of the contraband, The Post has learned.

The head of the officers’ union charged that the order came straight from Mayor de Blasio, who promised to bring more transparency to city government, but has been slammed by critics for doing the opposite.

“This is another attempt by Mayor de Blasio to keep the public in the dark about what’s going on in the schools. This is coming from City Hall,” said Gregory Floyd, head of Teamsters Local 237, which represents school safety agents. “He wants to fudge the numbers.”

Floyd said he got a threatening call from a lieutenant in the NYPD’s Brooklyn South headquarters asking how the Teamsters union got hold of photos of a BB gun confiscated Wednesday at Erasmus Hall HS.

Department brass also sent out a harshly worded warning ordering the school cops not to take or release photos.

“Under NO circumstances are [members of Service] allowed to take photographs of weapons, dangerous instruments and/or contraband confiscated or found on school grounds and forward the photographs [to] anyone outside of the police department without authorization,” it read.

News of the policy came the same week that three students were caught bringing pot to school — with one packing heat as well.

On Friday, a 16-year-old student brought a loaded handgun and six bags of weed stuffed inside his socks to Murry Bergtraum HS, which is just steps away from Police Headquarters, cops said.

Keanu Lopez was pulled aside by a teacher after a fellow student said the suspect smelled of weed, and was charged with possession of marijuana and possession of a weapon.

On Wednesday, a female student showed up to a Queens high school with 15 nickel bags of marijuana and a scale in her backpack — but she was let off with just a summons.

And a 15-year-old was arrested Friday at Flushing HS for bringing 13 bags of marijuana to school, cops said.

Ironically, Deputy Inspector Judith Harrison, commanding officer of the 109th Precinct in Flushing, tweeted out a photo of the seized pot later Friday.

Floyd said the city was getting too permissive by giving law-breaking students a pass, he said.

“They let her [the Queens girl] go to sell again. I’m surprised they didn’t give her back the marijuana,” he said.

City Hall did not respond to a request for comment.
