NEW YORK -- The FBI and New York Police Department say a reward of up to $115,000 is being offered for information leading to an arrest and conviction in the March 2008 bombing at the Times Square military recruitment station.
No one was injured. But Police Commissioner William Bratton says people had walked past just moments before the device detonated.
Officials say the explosion may be connected to earlier unsolved bombings at the British and Mexican consulates.
FBI footage shows the Times Square suspect placing the bomb and riding away on a bike.
Authorities say the explosive device used ammunition commonly found on battlefields in Iraq and Afghanistan.
In 2013, a $65,000 reward was offered for information related to the suspect or suspects involved in the bombing.
Surveillance footage released after the bombing showed a suspect riding a blue Ross bicycle to the scene and placing what is believed to be the bomb in front of the recruiting station.
The bombing took place on March 6, 2008, and the bomb itself was contained in a metal ammunition box. It produced a sudden flash and billowing cloud of white smoke. When the smoke cleared, there was no serious damage, and there still is not any clear indication of a motive.
The blast left a gaping hole in the recruiting station's front window and shattered a glass door, twisting and blackening the building's metal frame.
