One of the guys arrested had anti-tank ammo at his house:

Authorities now have three people under arrest as they conduct an investigation into unspent anti-tank shells found in a Raleigh metal scrap yard.

A federal agent says three Hispanic men were being held on immigration violations, but declined to elaborate about the case.

Disposal operations ended Friday at the plant. Raleigh police said Army experts detonated 34 explosive devices.

Sanford police say they found similar shells at one man’s home and were told it came from the Fort Bragg area.

The FBI didn’t offer much more information, but what they did is worth noting:

How the scroungers got the shells is still a mystery. An FBI spokeswoman in Charlotte said Friday that she couldn’t release any new information about the investigation.

Working from identification given to the scrap yard, investigators traced the explosives to Sanford, and the two men detained by the Sanford police said the munitions had come from the Fort Bragg area, said Sanford police Capt. David Smith. He declined to elaborate, saying he did not want to harm the federal investigation.

“That’s what the suspects told us in the course of our involvement,” he said. “They gave us specific information, but I can’t go into that.”

Smith said his department found several spent shells and at least one live artillery round in the yard of a home in Sanford.

A spokesman for Fort Bragg, Tom McCollum, said Thursday that base officials had no idea whether the munitions had come from Bragg or how someone might have acquired them if they did.

From what I can find so far, no one knows where all this ordinance came from.

I don’t know about you, but I find that disturbing.
