ADDS DATE OF ARREST - FILE - In this June 23, 2011 file photo, Mexican poet and peace activist Javier Sicilia holds his hands over his chest during a meeting in Mexico City. Mexican authorities say they arrested on Tuesday, Jan. 14, 2014, an alleged drug trafficker as a suspect in the killing of Sicilia's only child. Sicilia's son, Juan, and six friends were abducted by gunmen while leaving a nightclub in Cuernavaca, and their bodies were found abandoned near the city. The killing led Sicilia to become a vocal critic of the Mexican government's military crackdown on drug cartels. (AP Photo/Eduardo Verdugo, File)
