Detective ‘traumatized’ by NYPD officer’s murder, source says

An NYPD detective who was working security near the Park Avenue building where a madman killed four people had her reputation dragged through the mud in the aftermath of the slaughter.

Online rumor mongers claimed Det. Shareka Henry fled the scene when bullets were flying, police sources said.

At the time, Henry, 39, was working for a private security firm that covers 345 Park Ave. and 601 Lexington Ave, which is a block away.

She was at the Lexington Avenue building when Shane Tamura marched into 345 Park. with an AR-15 style assault weapon and opened fire. The victims included Henry’ Brother in Blue, Det. Didarul Islam.

“She saw Officer Islam being carried out,” a source involved in the investigation said. “She had seen him an hour earlier and got him an iced tea from Starbucks. It was still there at the scene.”

Online, the rumors reached a crescendo a couple weeks after the shooting.

“Armed NYPD Detective Shereka Henry observed the mass shooter approaching … with his long gun … and ran, hid, told no one,” read a post on a private Facebook group for cops that was shared with The Post.

It wasn’t clear who made the post from the copy that was being circulated.

The rumors of her leaving the scene were so persistent NYPD brass brought her in for questioning last Wednesday, police sources said. 

Investigators reviewed the NYPD’s Argus security cameras and body-worn camera footage from officers at the scene and saw that Henry ran to the scene not from it, the source said. 

“They have her on the plaza, but SRG (Strategic Response Group) and MTN (Midtown North Precinct) officers were telling everyone to stay back,” the source said. “You see her on body worn camera talking to cops.”

She’s also seen helping men and women who were being evacuated from the building while holding their hands up, the source said.

Internal Affairs discovered she was working the security gig for a firm hired by Blackstone Group LP, a public investment firm, without proper NYPD paperwork, so she was transferred from the Intelligence Bureau to a Bronx precinct’s detective squad.

That also fueled the “rumors and false information” that was “posted as fact” on social media, the source said.

“She definitely didn’t run from it,” the source said. “She ran to it. She’s traumatized.”

Henry recently was in the news when she was punched in the head while fighting a crazed man at a Midtown Starbucks after he was seen hurling products around the store, police sources said.

Henry could not be reached for comment.

“How many people are these rumor mongers going to throw under the bus?” a representative for the Detectives Endowment Association said.
