The suspect in the attempted Times Square bombing received $4,000 cash for the plot in a meeting at the Dunkin' Donuts store at the Ronkonkoma LIRR station, authorities said Friday, and the FBI is reviewing surveillance tapes from the store to see what it can learn about the transaction.

A U.S. law enforcement official said bombing suspect Faisal Shahzad, 30, a Pakistan-born U.S. citizen living in Bridgeport, Conn., received the cash at the Dunkin' Donuts in Ronkonkoma sometime before the May 1 failed car bombing. The official, who spoke on condition of anonymity, declined to say whom Shahzad said he met with or whether surveillance video from the store proved useful.

The store's owner, Uri Back, 48, of Roslyn Heights, said authorities asked for surveillance footage from the store. He said the surveillance system has 30 days worth available.

Dunkin' Brands Inc. spokeswoman Michelle King and a law enforcement source said the franchisee turned over 30 days of video to the FBI. Back said his store has been closed for renovations since April 20 but is to reopen next week.

One day after conducting raids on Long Island and in Massachusetts, Maine and New Jersey to follow the botched attack's money trail, investigators were looking at the video, financial records and a 3-inch-by-5-inch notebook where a Shirley man kept notes of a loan.

That man, Mohammad Iqbal, whose home was searched Thursday, said Friday that he never met bombing suspect Shahzad and that he would sue the FBI unless it apologized. "Once they apologize publicly, I'll be satisfied," he said.

He added that his 9-year-old son was concerned children at school would call him a terrorist. The FBI "came over here to harass me and my family," he said.

Iqbal said investigators were especially interested in his connection to Muhammad Younis, a Centereach man whom FBI agents also were seen talking to Thursday.

Iqbal said among items FBI agents seized was a 3-inch-by-5-inch black-and-white composition notebook. In it were records he made showing more than $8,000 he borrowed from Younis in 2005 when Iqbal and his brother needed the money to visit their sick father in Pakistan. Iqbal said he was not working in 2005 and didn't have the money. It took him two to three years to repay the loan, he said, adding that each time he repaid Younis, he recorded the amount in the notebook.

Meanwhile, law enforcement officials identified three men arrested Thursday in the raids. Aftab Khan and Pir Khan were arrested in the Boston suburbs, and Mohamad Rahman was arrested in Portland, Maine, all on immigration charges. Rahman had told his boss that he knew Shahzad but hadn't seen him for eight or nine years, The Associated Press reported.

Agents in New Jersey carted away computers and financial records from two locations, officials told The Philadelphia Inquirer.

U.S. Attorney General Eric Holder said Thursday "there is at least a basis to believe" the detained men gave Shahzad money, but added they may not have known what the money would be used for.
