Armenian police used unlawful force against demonstrators on several occasions during the protests in April and May, calling on the prime minister to resign, says the Amnesty International report. 

"On 12 June, police and demonstrators clashed in the centre of the capital, Yerevan, during protests against the border demarcation agreement. Some 101 individuals were injured, including 17 police officers, and 98 people were reportedly detained.

At least 15 individuals were later charged with hooliganism and violating public order. No law enforcement officers were indicted or charged following an inquiry into the proportionality and legality of the police response," says the statement.
