From [HERE] NYPD cops had a front-row seat to a five-on-one brawl — but let the violence play out rather than doing their jobs to break it up, The Post has learned.

An 11-year-old girl was slapped, punched, kicked and even shocked with a stun gun by a group of five other girls after a basketball game around 7 p.m. Sunday on East 125th Street near Madison Avenue in Harlem.

During the roughly 4-minute beatdown, cops sat idly in nearby cruisers — but they didn’t get out until the girl was bloody and bruised, a Post photographer observed.

At least 20 police cars were nearby on the street — with at least one a little more than a car-length away, photos show.

Police sources told The Post the young girl was treated at Mount Sinai Hospital after being cut, bruised and shocked in the stomach with the stun gun. The girl told cops she didn’t know her attackers but knew two of their handles on social media, sources said.

An NYPD spokesman claimed the account witnessed by the Post photographer was “completely inaccurate.

“The officers were met by a large crowd while attempting to come to this person’s assistance. They were outnumbered. Projectiles were thrown at them. And they were forced to reposition and call every available resource in the area,” said rep Al Baker.

The department also tweeted footage it claimed to show people throwing bottles at cops who tried to intervene — though it was unclear when or where the footage was shot, and it does not show the girl being attacked.

But the Post photographer said he observed no bottles being tossed at police — though he was on the scene after hearing reports of an unruly crowd nearby some 45 minutes prior.

It was not known if any arrests were made in connection with the fight.

The hands-off approach comes as the police unions challenge a portion of NYC’s chokehold bill that makes it a misdemeanor crime to use any technique during an arrest that could limit breathing.

Top NYPD officials have also spoken out against the local reform, calling it dangerous, but have denied a slowdown  — despite video leaking out from a weekly CompStat meeting capturing precinct leaders telling Chief of Department Terence Monahan that cops were “afraid” of facing charges over the law.

Over the last month, arrests have plummeted, with cops making nearly 60 percent fewer collars, according to NYPD statistics released Monday.

Cops are also pulling over fewer drivers, issuing a quarter of the normal speeding tickets — with the city’s speed cameras violation count holding steady.
