Hundreds of protesters staged a rally in Bahrain demanding the immediate release of an activist who has been imprisoned for three weeks without any criminal charges brought against him.

The demonstrators took to the streets in the northwestern village of Diraz, located west of the capital, Manama, on Monday to demand the freedom of Seyed Alawi Seyed Hussein, Arabic-language Bahrain Mirror news website reported.

Hussein was arrested at his office on October 24 by Yemeni regime forces.

The protesters held up Hussein’s pictures and chanted slogans condemning the ruling of Al Khalifah regime.

His family expressed serious concerns over his fate and his possibly worsening health condition.

They said he suffers from hypertension, gastrointestinal problems, and knee pain and swelling.

Hussein’s wife stated that authorities have not allowed him to contact his family and that her husband had received no summons prior to his detention.

The Manama regime declined to provide further information about Hussein’s charges and his place of detention.

The regime has waged a harsh crackdown on Bahraini people ever since February 2011, when anti-regime protests erupted in the small island.

Saudi Arabia and the United Arab Emirates deployed troops on March 14, 2011 to Bahrain to assist the Manama government in its crackdown on protesters.

Since the beginning of the popular uprising, scores of people have lost their lives and hundreds of others sustained injuries or been detained by the despotic regime.
