Luna said Sosa was apprehended by U.S. Border Patrol agents after he attempted to cross the border at an "undesignated checkpoint."

Sosa was turned over to Brownsville police and after questioning, confessed to the aggravated robbery, according to Luna.

The Cameron County District Attorney's office is seeking to certify Sosa to stand trial as an adult. The DA's office said he is a "continuing threat to the community."

Sosa was taken to Darrell B. Hester Juvenile Detention Center and is pending arraignment. He faces five counts of aggravated assault with a deadly weapon and one count of aggravated robbery.

Luna said additional charges may be pending.
