Ten violent leaders of the murderous Bronx-based “280” gang have been indicted on charges related to shootouts over the drug trade in the Morrisania section, authorities announced Monday.

The eight-count indictment describes a reign of terror as the gang fought turf wars with other Bronx gangs, including “Dub City,” “WTG” and “6 Wild.”

“Today’s indictments are the culmination of a much larger investigation into four of the city’s most violent street crews, who since 2011 were responsible for murders, shootings, gun trafficking and narcotic distribution throughout the communities of the Bronx,” NYPD Commissioner William Bratton said in a statement.

The busts were part of the NYPD’s “Operation Crew Cut,” in which 50 gangbangers were indicted and 24 weapons seized in the past 18 months, according to a statement from Bridget Brennan, the city’s special narcotics prosecutor.

The operation resulted in a marked 34 percent drop in shootings in the 44th Precinct and nearby areas, she said.

The 10 high-ranking gangsters were busted Friday and charged with conspiracy to commit murder, assault, narcotics possession and weapons possession. They were expected to be arraigned today.

Among those charged were the gang’s kingpin, Diamond “Bo Gotti” Brown, 21, and his top lieutenants Jesus “Juice Bambino” Perez, 20, and Guess “Guess Loc” Carter, 21, all of the Bronx.

“Over the past three years, these four warring gangs together were linked to 34 shooting incidents in which 43 individuals were shot. In some instances, gang members brazenly fired their weapons in public areas, including busy streets, at apartment buildings and in one case into a crowded restaurant. Several victims were innocent bystanders,” Brennan’s statement said.

Cops scrutinized social media as part of the probe, gathering evidence from Facebook, YouTube and Instagram, which the thugs used to talk trash about rivals and recruit new members.

Innocent bystanders were often wounded during the shootouts between rival gangs.

On July 28, 2011, a member of “6 Wild” fired into a crowded restaurant where members of “280” were gathered and one “280” member was shot, according to the statement.

Later that year, on Sept. 11, 2011, members of “280” and “WTG” exchanged gunfire at a “WTG” YouTube video session, and two bystanders were shot.

Brown, Brennan said, authorized many of the hits.

In August 2012, Brown sent a barely literate message to a new recruit demanding cash for guns.

“YU GOTTA ATLEAST PUT IN MONEY 4 dhat set severy chance yu get…cause dhis beef s–t aint cheap” and “im supplyin dha hood soo wee can stay on dha map,” Brown wrote, according to the statement.

“Reckless, wanton shootings detailed in the indictment forced innocent bystanders to take cover and neighborhoods to conduct daily business in great fear for their safety and security. Targeting drug gangs involved in violence has significantly diminished shootings in these neighborhoods,” Brennan said.

Others busted in the sweep include Anton Pye, 18; Issiah Kirkland, 23; Jaquan Murray, 19; Benjamin Banks, 21; Cheyenne Carter, 18; Brian Harris, 18; and Davon Poole, 19, all of the Bronx.
