The truck was found shortly after it disappeared, but the radioactive material remained missing, National Civil Protection Coordinator Luis Felipe Puente posted on his Twitter account.
Puente confirmed a few hours later that the radioactive material had also been located.
The container "was not violated, it contains the material, which was measured," he added in an interview with Milenio television.
“Hey, better shut up about this or some Americans might want to control their border.”
“S’okay, boss! We found it!”
