An illegal migrant violently raped an incapacitated man behind a dumpster outside a Long Island restaurant, officials and law-enforcement sources told The Post on Monday.

Suspected heinous Honduran national Jose Ignacio Bonilla Garcia, 32, was later nabbed by authorites in the nick of time — as he tried to flee across the border in Texas, authorities said.

Garcia had dragged the drunken, passed-out stranger away from the Esperanza Deli Café in Amityville just before midnight March 27, pulling the victim’s unresponsive body behind a dumpster and raping him, police said Monday — noting that the entire attack was caught on surveillance video.

The victim regained consciousness at one point during the horrific assault and tried to fight back, prompting Garcia to pick up a large piece of wood and beat him with it until he went limp again, police said.

The rapist then fled, leaving the man for dead, cops said.

The victim wasn’t found until hours later by a delivery driver, who spotted his unconscious body and called 911, according to police.

The wounded man was rushed to Good Samaritan Hospital, where he was treated for his injuries and underwent a sex-assault exam, which recovered DNA evidence that pointed to Garcia, officials said without elaborating.

But by the time police had recovered all of the evidence, Garcia was already long gone from the area, hopping on a Greyhound Bus headed to the southern border, authorities said.

US Marshals then tracked him down to Rosenberg, Texas, and took him into custody before extraditing him back to Suffolk County.

“Accountability for perpetrators of sexual violence is not just a legal obligation, but also a moral
one,” Suffolk County District Attorney Ray Tierney said in a statement.

“My office will do everything in its power to ensure that those who commit such heinous acts are held accountable, not just for the sake of justice, but to protect others and to send a clear message that these crimes will not be tolerated in Suffolk County.”

Garcia was arraigned Monday on two counts of first-degree rape and one count of second-degree assault and remanded without bail. He faces up to 25 years behind bars if convicted on the top count alone.

He is due back in court May 28.

The Department of Homeland Security has already lodged an immigration detainer to have Garcia deported after his prosecution.
