released sunday night that shows a man walking away from the suv. he's wearing a dark-colored shirt. he stops. he keeps looking back -- the police say he keeps looking -- there it is. he takes his shirt off, he keeps looking over his shoulder. that's back in the direction of the suv. he takes off a dark-colored shirt. below he's wearing a lighter colored shirt. i think they released that tape because they thought it looked like suspicious behavior, could have been someone trying to conceal his identity. and frankly, i heard conflicting things about whether investigators think whether that is in fact the person they arrested today. we'll hear more about that in the coming hours today. >> we understand that authorities visited pennsylvania tourists who had video as well. did anything come from that? >> they did. there was a tourist who was in the area photographing the mounted policeman -- was interested in the fact that there were mounted police in times square.
