Investigators have identified the two men who they say took a suitcase concealing a pressure cooker bomb left behind by the suspected Chelsea bomber.
The FBI released photos of the two men last week.
They were seen in security footage removing the bomb from inside the travel bag on a 27th Street sidewalk.
They say the men walked away with the luggage, leaving the device behind.
A law enforcement official told the Associated Press that the men were Egyptian tourists who since returned home.
Investigators notified Egyptian officials they want to question both men, but don't believe they were involved in the attack.
Meanwhile, bombing suspect Ahmad Khan Rahami remains in a New Jersey hospital after being injured in a shootout with police last week.
He's facing federal charges but has yet to appear in court.
