The owner of the limo company involved in Saturday’s deadly upstate crash served as an FBI informant in a 2009 terrorist bomb plot targeting two synagogues in Riverdale and an Air National Guard base.

Prestige Limousine Chauffeur Service owner Shahed Hussain, 62, of Gansevoort, NY, testified at the 2010 Manhattan federal-court trial of four men he recruited into an FBI sting operation after infiltrating a mosque in Newburgh.

All four were convicted.

Hussain also helped convict the imam of an Albany mosque he infiltrated for the feds as part of a 2003 sting operation involving a scheme to sell a surface-to-air missile to terrorists in Pakistan.

He began working for the feds in 2002, after he was busted for running a scam to help drivers cheat on state DMV tests while he was working as a translator for the agency.

Hussain’s address is listed as the Crest Inn Suites and Cottages in Gansevoort, a string of 23 run-down motel units that manager Arnie Cornett, 60, described Monday as “transitional housing.”

Cornett identified the owner of the limo company as “Mr. Malik,” who he said lives in Dubai. Hussain used the name “Malik” when he was involved in the Albany sting, according to local reports at the time. Authorities said Monday that Hussain was not in the US.

Records tie Hussain’s sons, Shahyer and Nauman, to a sprawling, seven-bedroom home outside Albany.

Neighbors said they saw “stretch limos and young Russian girls coming and going at all hours” before the two men suddenly moved out Sept. 30, leaving a “mountain of garbage” outside.

Neither returned messages.
