An HIV-positive New York man was arrested December 8 and charged with reckless endangerment and criminal possession of a forged document that claimed he had tested negative for the virus, the Brooklyn Daily Eagle reports. The man allegedly forged the document and presented it to an unnamed woman so she would have unprotected sex with him.

According to the article, the woman had asked 47-year-old Duane Lang for proof of his HIV-negative status before agreeing to unprotected sex. Lang allegedly forged a document—dated December 12, 2007—saying he was “negative/non-reactive for the HIV-1 antibody based upon the rapid HIV antibody test,” which was supposedly from the AIDS Center of Queens County, where Lang had worked previously as a volunteer.

When the woman later questioned Lang about the document's authenticity, he admitted that it was fake and that he had tested HIV positive in 2002. Lang faces up to eight years in prison if convicted.
