According to the affidavit for arrest, Wilson courted the 16-year-old victim on a dating website designed for successful men to meet younger women.
Taiwan's Criminal Investigation Bureau (CIB) told Taiwan News that Wilson could not be arrested for a crime, but if he was caught he could be deported back to the U.S. in accordance with their immigration laws.
On Wednesday, September 19, in Wilson's hometown of Austin, Texas, an arrest warrant was issued for the 3D-printed gun rights activist related to his alleged sexual assault of an unnamed underage girl.
The victim disclosed the details about the incident to a counselor, who informed Austin police. The National Immigration Agency is now urging the American Institute in Taiwan to issue a valid travel document for Mr Wilson, so he can be deported back to the US accordingly.
While Taiwan has no formal extradition treaty with the USA, and Wilson was not said to have been doing anything directly criminal in Taiwan, the press there reports that he was arrested without incident because the US had revoked his passport, making his mere presence in Taiwan illegal.
Ars confirmed via email that the US Marshals Service is fully aware of the situation.
Wilson is the founder and director of Defense Distributed, a nonprofit that publishes open-source gun designs. They met in Austin on August 15 where Wilson brought her back to a hotel room.
She said that he later identified himself as "Cody Wilson" and claimed to have been 'a big deal'.More news: India calls off meeting with Pakistan, MEA says Pak's evil agenda exposed
"We know that Mr. Wilson frequently travels for business", Officer said.
Wilson sexually assaulted her and then "retrieved five $100.00 bills from a bag on the floor" and gave her the money, the alleged victim told police, according to the affidavit.
It is not clear why he went to Thailand specifically, Officer said.
Wilson flew to Taipei on September 6.
Wilson is a self-described "crypto-anarchist" at the center of a fierce legal battle over whether Americans should be able to print guns that would be unregulated and untraceable.
Years of litigation followed, leading to a settlement in July allowing Wilson to re-release the gun's downloadable blueprints.
Later that month, Wilson said he'd started selling the plans for producing plastic firearms using 3-D printers despite an injunction blocking it because of concerns about public safety.
