The FBI has released a new photo of the two men who took the suitcase containing the undetonated pressure cooker left on 27th Street by suspected Chelsea bomber Ahmad Khan Rahami, and officials believe the duo might have been tourists who have since left the country.

The two men were seen on surveillance video removing the bomb from luggage on West 27th Street between 6th and 7th Avenues at around 8 p.m. on the night of September 17th. They left with the luggage, and though law enforcement officials do not think they were aware the device was a bomb, they are hoping to recover the luggage and use it as evidence.

An explosion occurred on West 23rd Street, between 6th and 7th Avenues, at 8:30 p.m., injuring dozens. The device on West 27th was found around 10:30 p.m. (a resident initially thought it was a "kid's science experiment") and removed by authorities.

"I think they were more interested in the bag, not what they were taking out," Jim Watters, chief of the New York Police Department's counterterrorism unit, told ABC 7, adding that they were "very, very lucky" the bomb didn't explode.

DNAinfo reports that the two men might actually have been tourists from out of town, since investigators say no one has come forward to confirm their identities. "You can see them inspecting the bag, turning it around and talking about it as though they are saying it is not bad, and looks pretty good, and walk off with it,” a source told the website. The men are believed to have accidentally deactivated the device when they removed it from the suitcase.

Meanwhile, Rahami's father, Mohammad Rahami, told ABC 7 in an interview that his wife, Najiba, and son, Qassim (who is a US citizen) were pulled off a flight in Dubai and questioned for 16 hours, and are now being detained in Afghanistan. "Why send my son back to Afghanistan? He is a U.S. citizen. You have any questions? Bring him home, (don't) send him to a different country," Rahami said.

The elder Rahami has repeatedly claimed he warned FBI officials that Ahmad Rahami was watching jihadist and Al Qaeda videos. He told ABC 7 his son was "not a human being... not a Muslim. If you're Muslim, you respect your father. If you're Muslim, you respect religion. If you're Muslim, you respect your country,"
