NEW YORK >> A reward of up to $115,000 is being offered for information leading to an arrest and conviction in an unsolved 2008 bombing at the Times Square military recruitment station, the FBI and New York Police Department said Wednesday.

No one was injured in the blast, which happened before dawn on March 6, 2008, but someone could have been, Police Commissioner William Bratton said.

"Moments before the device detonated, individuals walked by, unaware of the potential danger and imminent explosion," he said.

Officials said the explosion may be connected to other unsolved early morning bicycle bombings in New York: one at the British Consulate in May 2005 and the other at the Mexican Consulate in October 2007.

FBI footage shows the Times Square suspect placing the bomb and riding away on a blue bike that was later found in a trash bin in an adjoining neighborhood.

The device was built using an ammunition can commonly found on battlefields in Iraq and Afghanistan, authorities said.

"It was filled halfway with black powder and detonated using a time fuse," the law enforcers said in a statement. "Although no one was wounded, the device could have caused significant casualties if people had been close to the blast."

"Someone knows those responsible for placing this device in the heart of New York City," said FBI Assistant Director-in-Charge Diego Rodriguez. "We need those people to come forward to help us solve this crime before they can strike again."
