The driver who allegedly killed eight people in the Manhattan terror attack was interviewed by feds in 2015 — but officials didn’t have enough information on him to open a case, according to a new report.

Sayfullo Saipov’s name and address were listed as a “point of contact” for two men whose names were on the Counterterrorism and Criminal Exploitation Unit’s list after they arrived in the US from “threat countries,” a federal source told ABC News.

Saipov was interviewed two years ago in Paterson, New Jersey, where he has a current address. The 29-year-old Uzbek native came to the US through a Diversity Visa Program lottery in 2010 — making him a legal permanent resident.

His social media activity has linked him to others who are or were subjects of terror probes, ABC said. But it’s not clear whether he was part of a cell or directed to carry out Tuesday’s deadly attack.

Saipov was carrying a note pledging allegiance to ISIS and an image of the Islamic State flag inside his Home Depot rental truck, which he used to plow into people along a bike path on the West Side. Eight people were killed and 11 injured.

A spokesman for the Department of Homeland Security said its agencies — including Customs and Border Protection, Immigration and Customs Enforcement and Homeland Security Investigations — did not interview Saipov in 2015.
