A top human rights activist was taken into custody on Saturday by Bahraini authorities after arriving at the country’s airport.

Maryam al-Khawaja, the co-director of the Gulf Center for Human Rights, flew back to her native country to visit her father. Abdulhadi Abdulla Hubail al-Khawaja, also an activist, has been detained by the kingdom since 2011 and is currently on hunger strike.

According to Maryam’s Twitter feed, she has been charged with insulting the king, assaulting a police officer at the airport, and engaging in a human rights campaign called Wanted For Justice. She is expected to be held in prison and interrogated – without access to her lawyer.

As her lawyer I have filed a legal complaint to the public prosecution for preventin me from talking to my client before the interrogation.

“Maryam told me that she will be transferred to the court tomorrow,” her mother, Khadija al-Musawi, told Reuters.

The U.S. Navy’s Fifth Fleet, which commands naval forces in the Persian Gulf, is located in Bahrain. The Gulf country has been contending with protests and civil unrest since 2011.

Bahrain recently expelled U.S. Assistant Secretary of State for Democracy, Human Rights and Labor Tom Malinowski from the kingdom for meeting with opposition figures. Malinkowski served as Washington Director of Human Rights Watch before taking his position at the State Department.
