FBI agents arrested three men Thursday as they pursued new leads in the Times Square Bombing case and conducted a number of raids across the Northeast. Media reports indicate that the arrests are focused on "cash couriers" potentially involved in the Pakistani Taliban's funding of the terrorist attempt.

The raids targeted homes and businesses in Massachusetts, New York and New Jersey. Warrants were executed at a Mobile gas station (Harvard Street) in Brookline, Massachusetts and a home in Watertown, Massachusetts. Additional warrants were served at Prompt Printing, a printing shop in Camden N.J.; a home in Cherry Hill, New Jersey; and two locations on Eastern Long Island in Suffolk County, New York.

Two of the suspects arrested were from Massachusetts and a third from Maine. All were detained on immigration violations, including one "visa overstay." CNN reports that the initial two suspects may have been "collateral" arrests, without direct knowledge or input in the attempted bombing.

The raids are part of the government's attempt to use intelligence collected from Faisal Shahzad, who has already admitted his involvement in the case as a lone bomber. Attorney General Eric Holder told a House committee hearing:

"These searches are the product of evidence that has been gathered in the investigation since the attempted Times Square bombing and do not relate to any known immediate threat to the public or active plot against the United States… I share that information just to indicate that this is an ongoing investigation and that we are actively pursuing all those who were involved in it."

While Shahzad is believed to have acted alone in trying to explode a car bomb in Times Square May 3, investigators have wondered where he got the money to travel to Pakistan, to buy materials for the bomb or buy the Nissan Pathfinder he hid it in.
