NYPD: Video may show SUV bomb suspect

NEW YORK (AP) - Police investigating a terror attack that could have set off a deadly fireball in Times Square focused Sunday on finding a man who was videotaped shedding his shirt near the SUV where the bomb was found.

Police said the gasoline-and-propane bomb was crude but could have sprayed shrapnel and metal parts with enough force to kill pedestrians and knock out windows on one of America's busiest streets, full of Broadway theaters and restaurants on a Saturday night.

The surveillance video shows an unidentified white man in his 40s slipping down an alley and taking off a shirt, revealing another underneath.
