Guilty: Andras Janos Vass, 25, has been convicted of human trafficking and racketeering . A Hungarian man has been convicted of luring young, gay Eastern European men to the United States for a horrific life of sex slavery. Andras Janos Vass, 25, was found guilty of human trafficking and racketeering felonies this week after grooming fellow Hungarians online then keeping them captive in New York City and Miami. Vass brought men to America with the promises of easy work and high wages - then took their travel documents, threatened their families, and made them spend 20 hours a day on sex work, prosecutors said. He was found guilty of the offences by a jury in Miami-Dade on Thursday, the Miami Herald reported. He faces a maximum sentence of 155 years in prison - and will spend at least 21 behind bars. Three of Vass's victims testified against him at the trial. Two said they were tempted to the United States after being contacted via Planet Romeo, a free dating site. According Gay Star News, the men believed they would be employed as legal escorts and make between $3,000 and $5,000 a month. The victims said they were flown to New York City in 2012 and forced to live in a tiny one-bedroom apartment. They were forced to perform sex work at all hours, either in person or live on webcams. Lure: Prosecutors said at least two of the victims were lured to America via the Planet Romeo gay dating website . According to online listings, Vass's company, Never Sleep Inc., was based at an address in Sunset Park, Brooklyn in New York City. In August 2012, prosecutors said, the Vass and his associates moved the business to Miami. Vass is accused of running the sex ring with two other men, Gabor Acs and Viktor Berki, who have yet to stand trial. Victims said that they had their passports taken when they arrived and that Berki, a former policeman, threatened their families in Hungary. Vass is due to be sentenced on June 2.
