3D-printed gun pioneer Cody Wilson charged with sexual assault
A Texas man who has played a central role in making 3D-printed weapons available has been charged with sexually assaulting an underage girl.
A warrant was issued for Cody Wilson but he flew to Taiwan before he could be detained, police in Austin said.
A 16-year-old girl alleged she was paid $500 (£380) to have sex with Mr Wilson at an Austin hotel, they said.
Mr Wilson has been at the centre of a legal battle over publishing blueprints that instruct people on making a gun.
Mr Wilson has not yet commented on the case and no lawyer has yet issued a statement.
What are the allegations against Mr Wilson?
Austin Police Commander Troy Officer told a press briefing that a counsellor who had spoken to the girl informed police on 22 August that "that a juvenile female under the age of 17 had reported having sexual contact with a 30-year-old male".
The legal age of consent in Texas is 17.
Commander Officer said the girl met Mr Wilson through the sugardaddymeet.com website and had sex with him in a hotel on 15 August.
Police confirmed the girl's story through "videotape and interviews", he said.
The alleged crime is punishable by up to 20 years in prison.
