A Florida teacher was arrested for allegedly having sex with a 16-year-old high school student, authorities said. Waleska Velasquez, 29, a science teacher at Miami Jackson Senior High, was arrested Wednesday and release on bond Thursday, The Miami Herald reported. Police say Velasquez, charged with three counts of having sex with a minor, has confessed to having sexual relations with the student, who is now 17, starting in August 2009 and continuing through 2010. Velasquez told investigators she gave the boy gifts, cash and a cellphone she used to send him romantic texts and photos of herself nude and in sexy lingerie. Velasquez was hired by the Miami-Dade district in 2007. In light of her arrest, the district \"will work toward a swift termination,\" district spokesman John Schuster said. \"The district regularly reminds staff that personal relationships with students are unethical, forbidden by school board rules and may be illegal, as in this instance,\" Schuster said.
