Authorities caught the man who allegedly shot up an illegal Bronx social club, killing one and injuring two others, as he tried to board a flight out of the country, police and sources said.

The alleged triggerman, whose name was not immediately known, was picked up at John F. Kennedy International Airport’s Terminal 4 with a ticket to the Dominican Republic, according to police sources.

The man was wanted in connection to a shooting at a Fordham Manor club on Jerome Avenue near around 7 a.m. Monday, police said.

Wendolin Ortiz, 19, was shot and killed in the latest act of gunplay, which also left two others injured — a 28-year-old man and a 30-year-old man. Both men were expected to survive.

A spokesperson for the Port Authority Police Department, which patrols the airports, referred questions to the NYPD. The NYPD did not immediately have any information on the collar.
