Rights groups concerned over welfare of detained Venezuelan attorney and activist Rocio San Miguel

Representatives of nearly 10 human rights organizations held a press conference on Wednesday, demanding the immediate release of a prominent attorney and activist detained last week. San Miguel was detained Friday at the airport near the capital, Caracas, while she and her daughter awaited a flight to Miami. Attorney General Tarek William Saab accused her, without offering any evidence, of having a link to a plot to kill President Nicolás Maduro and other officials and attack military units.
