Yoani Sanchez, a Cuban dissident blogger, was arrested by Cuban government authorities after they accused her of planning a "media show" to disrupt the trial of a Spanish activist.
Sanchez, a well known blogger in Cuba and a vocal critic of the Castro regime, and her husband, Reinaldo Escobar, were arrested on Thursday as they traveled to Bayamo to cover the trial of Spanish politician Angel Carromero.
Carromero is on trial on manslaughter charges relating to a traffic accident where his car hit a tree and crashed, killing two passengers, Cuban activist Harold Cepero and Oswaldo Paya.
A BBC New report states Cuban officials announced Sanchez was arrested with her husband because they planned a "provocation" and "media show" that could endanger the credibility of the trial.
The U.S. State Department has called the arrest the "latest crackdown" on journalists.
State Department spokesman William Ostick told CNN: "We are deeply disturbed by the Cuban government's repeated use of arbitrary detention to silence critics, disrupt peaceful assembly, and impede independent journalism."
This is not the first incident of the Castro government harassing Sanchez. According to a Wall Street Journal report, in 2008 she was "roughed up" and has been denied permission to leave Cuba on several occasions to pick up various journalistic awards.
France24 states Sanchez and her husband were taken to a Ministry of Interior facility following their arrest. They were separated and "treated a little roughly".
According to Reuters, were Sanchez and her husband were released late Friday. In a phone interview she told the news organization: "Now I'm home, with a little stress, but back in my house."
