New York ( CNN ) -- Two Mexican brothers have been extradited to the United States to join a third brother to face sex trafficking charges in New York as part of a complex collaborative effort to combat human trafficking , federal officials said Monday . Benito Lopez-Perez , 32 , and Anastasio Romero-Perez , 39 , were arraigned on a 25-count indictment Monday morning in Brooklyn Federal Court , the U.S. attorney and the Justice Department said in a news release . The extensive indictment is the product of the Bilateral Human Trafficking Enforcement Initiative , an in-depth partnership involving the Department of Justice , Immigration and Customs Enforcement , Homeland Security Investigations , the Urban Justice Center and many non-profit and non-governmental organizations in the United States and Mexico , the release said . `` The indictment charges the defendants with sex trafficking , interstate prostitution , alien smuggling and money laundering offenses , involving victims as young as 14 and 15 years old , '' it said . On December 3 , the third brother , Jose Gabino Barrientos-Perez , 51 , was extradited from Mexico to face the same charges , officials said . U.S. Attorney Loretta E. Lynch also announced the extradition last month of Antonio Lira-Robles on the same charges . All the extraditions resulted from the comprehensive anti-trafficking program , which has so far resulted in the indictment of 52 defendants on sex trafficking charges and has `` rescued over 100 victims , including 17 minors , '' the release said . `` The sex trafficking of young girls and women is modern-day slavery we will do everything in our power to eradicate , '' Lynch said in a news conference Monday . She also announced the reuniting of a victim of sex trafficking with her child after a separation of more than 10 years . The mother was involved with the Carreto family sex trafficking ring , officials said . The ring operated between Mexico and United States from 1991 to 2004 , the Justice Department said upon Carreto 's sentencing in 2009 . United States v. Carreto is considered to be `` one of the first sex trafficking cases prosecuted by the United States Attorney 's Office in Brooklyn , '' according to Monday 's news release , `` After substantial post-conviction investigation and international coordination , the child was located and reunited with the victim-mother . '' Sienna Baskin , co-director of the Sex Workers Project at the Urban Justice Center , called this `` an example of people going above and beyond and being creative and thinking outside the box in order to make this happen . Now we need the lessons we learned in this case to be institutionalized . '' Baskin said she and others working as a part of the ad hoc task force realize that the fate of the victims is just as important as the fate of the traffickers . Under the initiative , `` the United States and Mexico have collaborated to bring high-impact prosecutions under both U.S. and Mexican law to more effectively dismantle human trafficking networks operating across the U.S.-Mexico border , '' Monday 's news release said . `` The extraditions over the weekend followed by the arraignments today are a testament to our resolve to bring justice to those charged with forcing young women into prostitution , '' James T. Hayes Jr. is the special agent-in-charge of Homeland Security Investigations in New York .
The Perez brothers have been extradited to the United States . A spokesman for the U.S. attorney's office in San Francisco said that a federal grand jury indicted them on charges of conspiracy and money laundering conspiracy. The indictments are a result of the Bilateral Human Trafficking Enforcement Initiative .
