The alleged members of the Dominican-based Trinitarios gang all face charges of racketeering, narcotics conspiracy and gun trafficking

Suspects accused of selling guns and drugs.

Authorities collared 38 Bronx and upper Manhattan gangbangers Wednesday after a two-year probe into a notorious crew, officials said.

The alleged members of the Dominican-based Trinitarios gang all face charges of racketeering, narcotics conspiracy and gun trafficking, authorities said.

The undercover investigation — which involved officers from the NYPD, the federal Drug Enforcement Administration, the Bureau of Alcohol, Tobacco and Firearms and Homeland Security — netted about $25,000 worth of drugs and 12 firearms in Wednesday’s raid, police said.

One weapon recovered, a Mac-11 machine gun, was painted the same shade of green the gang uses in its colors.

Federal prosecutors said the crew committed and planned violent acts, including murder, to protect its turf from rival gangs that include the Bloods, Crips, the Latin Kings and Dominicans Don’t Play.

“We believe we put a big dent in the Trinitarios gang,” said Capt. Lorenzo Johnson, the commanding officer of the NYPD’s Bronx gang squad.

Six people who were connected to the gang members were also arrested, police said. Authorities were still looking for about 12 other members of the gang.

Prosecutors said the Trinitarios sold firearms, including semiautomatic rifles, a shotgun and handguns, and transported them across state lines.

Numerous members of the Trinitarios who were arrested are also members of a smaller splinter gang, the Bad Boys, prosecutors said.

Johnson said most of suspects were already “known to the department in some manner,” and had long terrorized several blocks in Washington Heights and parts of the Bronx, including Marble Hill.

“Anytime we can help the community feel safer is a good day,” he said.
