Authorities looking for clues in the failed Times Square bombing attempt expect to release another video in the case, New York Police Commissioner Ray Kelly told CNN's "American Morning" on Monday.

Kelly said a video obtained from a tourist shows a person apparently "running north on Broadway."

Authorities earlier released a video showing an image of a man changing his shirt along a New York street. A balding man with dark hair is seen removing a shirt and putting it in a bag before walking out of the camera's view from inside a restaurant.

"These are not suspects," Kelly said. "These are people we would like to speak to."

Detectives have been poring over these and other items since Saturday night, when a Nissan Pathfinder containing bomb-making materials was found on West 45th Street in Times Square after a T-shirt vendor alerted police to smoke coming out of the vehicle.

Kelly said the video of the man taking his shirt off was one of the first authorities obtained, and it is from one of the many cameras in Times Square. The man is also of interest to Homeland Security Secretary Janet Napolitano, who told CNN's "American Morning" on Monday that authorities want to identify and speak to the man in the video.

Kelly said, "We thought it warranted an interview. He was taking his shirt off. This was a warm day. This happened just around the time that the pops start to go off inside the car. So that's why we simply want to talk to him."
