The NYPD is probing why two cops didn’t render any apparent aid to Lesandro “Junior” Guzman-Feliz as he bled to death on a sidewalk last week following a vicious gang attack, The Post has learned.

“The Bronx Borough command is reviewing the response,” NYPD spokesman Phil Walzak said.

Guzman-Feliz, 15, was butchered by a pack of at least five suspected Trinitarios gang members outside a Bronx bodega at 183rd Street and Bathgate Avenue last week.

The mortally wounded boy stumbled toward nearby St. Barnabas Hospital before collapsing on the sidewalk just steps away.

Cellphone video shows him splayed on the ground covered in blood as neighbors try to stanch the bleeding with what appears to be napkins. Two police officers can be seen in the video watching from the wings, but not doing anything to render aid.

“Yo, what are y’all doin’ about this?” one person can be heard shouting. “In front of St. Barnabas Hospital, man.”

The neighbors meanwhile try frantically to help and comfort the boy during his final moments.

“Junior, you’re good. You’re good, bro. Just keep talking,” one of the good Samaritans can be heard pleading with the dying boy.

“Just stay with us.”

Sources said the probe into the cops was initially conducted by the Internal Affairs Bureau. Walzak would only say there is no current IAB investigation.

He defended the officers’ response.

“There have been no complaints filed regarding the response to the incident, and there is no [Internal Affairs Bureau] investigation,” Walzak continued. “Officers responding to a different call were flagged down by civilians and directed to the victim, and an ambulance arrived just over one minute later.”
