A 9-year-old Bronx boy was shot dead in a botched robbery earlier this week in the Dominican Republic –  and cops arrested a pal of the boy’s dad on Friday.

Gioser Luís Feliz took a bullet to the head after the car he was traveling in was swarmed by a gang of robbers soon after he and his father left Santiago’s Cibao International Airport on Wednesday.

The boy and his father, Sergio Luis Feliz, had just flown in from New York’s JFK airport and were en route to a relative’s house when the violence unfolded, Univision reported.

Six men were arrested in connection with the fatal shooting, including Tomás Peña Morel, 32. Sources told Diario Libre that Tomacito was a friend of Feliz who would have known the family’s travel route and itinerary.

The suspects, who were in a rented car, allegedly followed the family from the airport and opened fire when the family’s driver refused to pull over after going through a toll booth, according to cops.

Gioser was rushed to a nearby hospital, where he was pronounced dead.

The gunmen fled the scene but were tracked down by cops less than 24 hours later.

Luis Ángel Vargas Brito, Derlin Javier Mercado Martinez, Cesar Junior Ulloa Cuevas, José Manuel Almonte Santana and Elian Martínez Sánchez were all taken into custody over the fatal shooting.

Police said the suspects subsequently confessed to shooting up the vehicle.  

Investigators haven’t said whether the fatal ambush was targeted or random.  

Meanwhile, Dominican Republic President Luis Abinader decried the deadly violence, tweeting on Thursday: “Since I found out about the death of the child Gioser Luis Féliz, I am following up on the case.

“I have been informed by the Director of the National Police about the arrest of the 5 criminals who committed this horrendous crime. Now justice must be ensured in the courts.”

Preparations are now underway to transport the boy’s body back to the Big Apple.
