Costa Rican police say the 22-year-old man, who was identified only by his two last names, Caicedo López. He is accused of visiting the Facebook page of one of the concert promoters and writing a threat in Arabic, warning of acts of violence at the singer's concert, which was scheduled to be held July 9 at the Coca Cola Amphitheater of Parque Viva in La Guácima, Alajuela.
