"Police units of Yerevan detained 165 people suspected of involvement in unrest," police spokesperson told RIA Novosti.
Earlier in the day, the country's Health Ministry said that Yerevan's medical centers received 60 people which sustained injuries in skirmishes erupting late on Friday.
On July 17, an armed group took several police officers hostage at the traffic police station in the Erebuni district of Yerevan. During the attack a policeman was killed and six more people were injured, including five police officers. Since then the group has released hostages, but captured ambulance staff, who came to the station to assist the wounded.
The group demands resignation of Armenian President Serzh Sargsyan and liberation of Jirair Sefilian, an opposition politician and founder of the New Armenia Public Salvation Front arrested over illegal arms storage.
