At least seven people were arrested at Newark Liberty International Airport in New Jersey on January 18, after allegedly attempting to film the smuggling of a fake bomb in a roller bag through a security checkpoint for a television show.
The suspects were charged with conspiracy, creating a public false alarm and interference with transportation.
Tom Carter, TSA's Federal Security Director for New Jersey, likened the stunt to be like shouting 'fire!' in a crowded theatre or using a toy gun to rob a bank, just to see what happened.
The nine individuals, all men, were charged and released, the Port Authority said.
"Inert device" is a technical term for a fake bomb.
Each of the group has been released without bail, though they could be fined $13,000 (£9,380) for each of the charges.More news: Def Leppard, Journey kick off tour at XL Center in Hartford
TSA spokeswoman Lisa Farbstein posted a photo of the fake device on Twitter.
The group did not make it past the checkpoint because TSA officers said they detected the item, which was concealed in a roller bag.
The device appeared to consist of wires and portions of a vacuum cleaner, among other things.
Endmol said in a statement that they were in contact with authorities and could not comment further on the case.
"While this process is ongoing we are unable to comment further but in the meantime, we sincerely apologize for any disruption caused", Holland said.
It's not known which TV network the group may work for or which TV show they may have been filming the encounter for.
