Members of the Civil Agreement opposition party were detained after a rally near the Yerevan police station taken over by an armed group had been dispersed, Civil Agreement party leader, Armenian parliament deputy and member of the Armenian National Congress opposition faction Nikol Pashinyan said.

Pashinyan had been negotiating with the police and the protesters for the purposes of avoiding clashes and had volunteered to speak to members of the armed group in the past few days.

"Party board chair Arayik Harutyunyan, board member Vilen Gabrielyan and about 15 party members staying with me were detained," Pashinyan said on Facebook.

Armenian police dispersed a rally near the Yerevan police station taken over by an armed group. About 50 people were detained, a source from Armenian police told Interfax.

Before the rally was dispersed, police twice warned the protesters about the intentions and urged them "to stop the illegal action."

As many as 51 people, including 28 policemen, were wounded in clashes in Yerevan on Wednesday evening. The protesters hurled stones at the police after their question about food supply to the armed group was left unanswered.

Later on, the protesters built barricades on Tigran Mets Avenue and the area near the seized police station.

A group of armed persons took over the police station in the morning of July 17. They killed a police officer and injured four people. They demanded that Founding Parliament opposition group leader Jirair Sefilian under arrest on the counts of illegal acquisition and storing of weapons be released. Other demands are resignation of the authorities and formation of a people's confidence government. Armenian police deputy chief Maj. Gen. Vardan Egiazaryan and Yerevan police deputy chief Col. Valery Osipyan were taken hostage amongst others.
