Times Square Bomber's Bike Found

March 7, 2008— -- Police believe they may have found the bicycle used as a getaway vehicle by the Times Square bomber and no longer believe that a taunting letter sent to members of Congress has anything to do with the explosion.

Federal officials are, however, reviewing a stop made on the Canadian border a month ago that may hold clues to the bomber's identity.

The bicycle was found several blocks away from the Army recruiting station that was hit by a small device early Thursday morning, blowing out its window.

The 10-speed bike looked relatively new, but was nevertheless dumped in the trash at Madison Avenue and 38th Street and found by a building superintendent who called police.

"I don't think anyone was seen leaving the bike," said New York City Police Commissioner Ray Kelly.

The bomber is seen on a grainy surveillance tape riding into Times Square early Thursday morning, getting off the bike and walking over to the recruiting center. Moments later, there is an explosion.

Later Thursday, police scrambled to review letters that were received by about 10 members of Congress. The mailed packets included a long anti-war manifesto along with a photo of a man standing in front of the recruiting center with the words, "Happy New Year. We did it."

But Kelly described the letter as "innocuous" and federal officials believe its arrival in Washington was just a bizarre coincidence.

The letters had a Los Angeles return address on them and police interviewed the man who lived at that address Thursday night. One thing that was clear is that the man was not in New York City early Thursday morning, sources said.

"I think the FBI has come to the conclusion that this individual is not involved," Kelly told CNN.

Of growing interest to investigators, however, is a stop made on the Canadian border about a month ago.

High level law enforcement sources told ABC News that the stop, made by Canadian authorities, has yielded evidence that may be linked to the bombing and that individuals are being sought in connection with the case.

Canadian authorities are not commenting on the matter either to confirm or deny, but sources told ABC News that U.S. and Canadian officials are reviewing the incident.
