At the time, he had been working in an upstate New York Department of Motor Vehicles office and ran afoul of the law for running a scam by helping test-takers cheat.
The manager also said that state police had come to the apartment complex on Sunday night looking to speak to Hussein, but the report did not state that they reached him there.
When Hussain was sentenced in 2006 for the DMV scam, a federal judge spared him additional prison time after prosecutors argued he had provided "substantial assistance" in the Albany terrorism sting as well as a drug and fraud case in which 12 defendants were convicted. Critics said Hussain induced the men to plot the crimes by offering cash payments. Aref was recently released, but remains in immigration detention pending his deportation to Iraq, according to the Times Union.
Hussain had emigrated to the U.S.in 1993 and still held a green card at the time he went to work for the Federal Bureau of Investigation, which credited him with helping arrest more than a dozen people, including the people involved in the DMV scandal and a member of an Afghan-based heroin trafficking ring.
Calls to the limousine company rang unanswered Monday.
During the Albany trial, there was testimony that the informant's recorded conversations with the Albany targets were in Urdu. Hussain was a key figure in the FBI's case against the so-called Newburgh Four-four Muslim men sentenced to 25-year prison terms after they were convicted for placing what they thought were bombs in a NY synagogue in 2010.
His cooperation resulted in the conviction of the four men in the thwarted plot.
Despite being exposed, Hussain never left the area, according to the Times Union.
Al-Akili, who was later convicted of a firearms charge, said he was approached by Hussain, who went by the name "Mohammed", and another man, who used the name "Shareef", when they turned up in his neighborhood and repeatedly made attempts to get close to Al-Akili. He said the men were "too obvious" and requested receipts even for small items they purchased like coffee and doughnuts.
The four men were impoverished and had no links to worldwide terrorist organizations. Earlier this week, the manager of the motel told local reporters that Mr Hussain now lived in Dubai.
The company also said it had "voluntarily taken our fleet of vehicles off of the road during the investigation" and had met with investigators with plans to do so again. Town officials asked that he keep the vehicles in Latham, where they had previously been stored when not in use.
"We're in possession of the airbag control module - what would be considered the vehicle's black box", State Police Maj Robert Patnaude said at a press conference on Monday.
Official records cited by news reports also show Prestige Limousines, the company that owns the limo, has been cited for 22 violations in the last 24 months, CBS News reported. The national average is 20 percent.
