Wilson was arrested at a hotel in Taipei Sept. 21 by Taiwan police assisted by the U.S. State Department.
According to police, Wilson met the underage girl through a website Sugar Daddy meet dot com and paid her $500 dollars for sex.
He is facing sexual assault charges in Austin, according to a statement from the U.S. Marshals service.
"This was a collaborative effort that demonstrates the dedication of local, state, federal and global officials working together to bring this fugitive to justice", said U.S. Marshal for the Western District of Texas Susan Pamerleau.
According to police paperwork, Wilson and the victim met face to face on the night of August 15 at a coffee shop on South Congress in Austin. The newspaper said he cooperated calmly with authorities upon arrest.
Wilson, who created blueprints for untraceable 3D-printed guns and posted them online, appeared in court in Houston after being deported from Taiwan, where he had fled after being told police were investigating allegations he had sex with the minor. Wilson later dropped her off at a Whataburger restaurant, she told authorities.
Not long after their alleged encounter, she told a counselor at the Center for Child Protection about it and they reported it to police.
Cody Wilson of the US, center rear, is seen at a police auto in Taipei. Nineteen states and the District of Columbia had sued the Trump administration to dissolve a settlement it reached with the company over allowing it to disseminate its designs for making a 3D-printable gun.
Nineteen states and the District of Columbia sued to stop an agreement that the U.S. government reached with Defence Distributed, arguing that the blueprints for how to print plastic guns could be obtained by terrorists and other criminals. However, he then began selling them for any amount of money to USA customers through his website.
Law enforcement officials worry the guns are easy to hide and are untraceable since there is no requirement for the firearms to have serial numbers.
Wilson, a self-described 'crypto-anarchist, ' has said 'governments should live in fear of their citizenry'.
