As the founder of Defense Distributed, Wilson became a notable figure in the US debate over guns after the company posted on the internet the blueprints for plastic guns that can be made with a 3-D printer.
The victim then told police that Wilson took her to the Archer Hotel at 3121 Palm Way.
According to police, Wilson met the underage girl through a website Sugar Daddy meet dot com and paid her $500 dollars for sex. "We don't know why he went to Taiwan, but we do know before he left, he was informed by a friend of the victim that she had spoken to police and police were investigating him for having sex with a minor", said Commander Troy Officer.
' That's our focus right now, ' Wilson's attorney, Samy Khalil, said in a statement Sunday night.
The blueprints allow people with 3D printing machines to make their own firearms, which are largely untraceable and not subject to typical gun-sales limitations and requirements.
The girl told authorities about their encounter last week but, police say, someone tipped Wilson off and he fled. The newspaper said he cooperated calmly with authorities upon arrest.
Cody Wilson, center rear, is seen at a police auto in Taipei on Friday last week.
Wilson owns a Texas company that sells blueprints for 3D-printable guns. Wilson later dropped her off at a Whataburger restaurant, she told authorities.
Over the summer, however, a federal judge temporarily stopped him from putting the blueprints online and in August, a federal judge in Seattle extended the injunction after a coalition of states and the District of Columbia said making untraceable plastic weapons available would create a public safety issue. The lawsuit by mostly Democratic state attorneys general argued that such weapons could be used by criminals or terrorists.
In 2013, Wilson - a self-described "crypto-anarchist" - successfully fired a bullet from the world's first 3D-printed handgun and posted its blueprint online. He then began selling them for any amount of money to US customers through his website.
Law enforcement officials worry that 3D guns are easy to hide and are untraceable since there's no requirement for the firearms to have serial numbers.
