The FBI and NYPD on Wednesday increased the reward for information on a still unsolved 2008 bombing at a Times Square recruiting station to $115,000 and disclosed that the bomb used a component typically found on battlefields in Iraq and Afghanistan.

"Even though no one got hurt, the potential was there," said NYPD Intelligence Division Chief Thomas Galati at a Foley Square news conference. "We want to make sure this doesn't happen again."

The news conference came near the seventh anniversary of the March 6, 2008, bombing, when surveillance video caught a man on a blue bicycle stopping between 3 and 4 a.m. near the United States Armed Forces recruiting station at West 43rd Street and Seventh Avenue to plant a bomb and light the fuse before fleeing on his bike.

Officials say they believe the cyclist may have had a lookout team of as many as five working with him. They have linked the case to bombs also placed by a cyclist between 3 and 4 a.m. at the British Consulate in May 2005 and the Mexican Consulate in October 2007, both in Manhattan.

The bomb, referred to as an "improvised grenade," was built with ammunition commonly used in Iraq and Afghanistan that was filled halfway with black powder and detonated using a time fuse, according to a news release.

Galati and FBI official Peter Tzitzis, special agent in charge of the New York Joint Terrorism Task Force, said they have classified the bombing as an act of domestic terrorism and have identified several "persons of interest," but still need the public's help.

"There is no statute of limitations on a dangerous attack that occurred in the heart of New York City," Tzitzis said.

A $65,000 reward was offered in 2013, but officials said none of it has been paid out in return for information. The FBI tip line is 212-384-1000.
