The president of the Bahrain Center for Human Rights (BCHR), Rajab was arrested upon return from Lebanon at the Bahrain International Airport in the capital, Manama, on May 5.
Sayed Yousif Almuhafda, a member of the BCHR, said Saturday that Bahraini police “had an arrest warrant from the public prosecutions office” to detain Rajab.
The charges leveled against the Bahraini activist include “participating in illegal assembly and calling others to join,” according to the BCHR.
Meanwhile, Bahrain’s Minor Criminal Court on Sunday postponed the trial of Rajab until May 22.
The arrest of Nabeel Rajab comes at a time when Saudi-backed regime forces continue their fierce crackdown on peaceful protests in the country.
On May 5, Bahraini police used tear gas and rubber bullets to disperse anti-regime demonstrators in the villages of Dair and Samaheej, located on the northern coast of the Muharraq Island.
Bahraini demonstrators hold King Hamad bin Isa Al Khalifa responsible for the death of protesters during the popular uprising that began in February 2011.
