Times Square bomber sought

Times Square returned to business as usual as police investigating the explosion at a military recruiting center looked at dozens of security videotapes, hoping to identify the bicycle-riding bomber.

Among the videos was one showing a hooded cyclist pedaling toward an area where a bicycle was found ditched in the trash, and another with someone walking away from the same spot, police said.

Investigators suspect the bike -- a 10-speed in good condition -- may have been used by the bomber in the attack just before dawn Thursday on a landmark military recruiting station. There were no injuries or serious damage from the bombing.
