Gun rights activist Cody Wilson reportedly fled from the USA state of Texas to Taiwan after getting tipped off that he was going to be charged for allegedly paying a 16-year-old girl $500 (£383) for sex.
Texas and federal authorities launched an global manhunt for Wilson after learning of his whereabouts overseas and that he missed a scheduled return flight home.
Cody Wilson holds a 3D printed gun, called the "Liberator", in his factory in Austin, Texas, on August 1, 2018.
A lawyer for Wilson did not immediately respond to a request for comment.
The American Institute of Taiwan cancelled Wilson's passport and Taiwan's National Immigration Agency said he therefore no longer had a legal status in Taiwan and was "now urging the American Institute of Taiwan to issue a valid travel document for Mr. Wilson, so he can be deported back to the United States accordingly".
"We are fully engaged with our worldwide partners on this matter", officials said in a statement. Wilson was arrested for illegally entering Taiwan after the USA cancelled his passport (Google Translate).
After he signed up to rent an apartment for six months, police located him and picked him up at a modest hotel in Taipei City's Wanhua District Friday evening. He fled to Taiwan when he learned USA police were investigating an accusation he had sex with an underage girl.
The victim disclosed the details about the incident to a counselor, who informed Austin police.
Authorities said Wilson traveled to Taipei shortly after and missed his flight back home.
Austin police issued an arrest warrant Wednesday on charges that Wilson sexually assaulted a 16-year-old girl last month in North Austin.
But before police in Austin, Texas could arrest him, they say he had already fled to Taiwan after a friend of the victim tipped him off that police planned on charging him several days prior.
Wilson faces up to 20 years in prison.
From there Wilson valet-parked at a North Austin hotel and checked in.
Nineteen states and the District of Columbia sued to stop an agreement that the government reached with Defense Distributed, arguing that the blueprints could be obtained by felons or terrorists.
Law enforcement officials worry the guns are easy to hide and are untraceable since there's no requirement for the firearms to have serial numbers.
