CAT/C/ARM/CO/4 20. The Committee is concerned at consistent reports of excessive use of force against protesters, including during the so-called Electric Yerevan protests of June 2015, when police used water cannons to disperse the demonstration and illegally detained 237 protesters. It is also concerned at the reported use of excessive force by law enforcement officials during the demonstrations of 17 to 31 July 2016, following the attack on a patrol service police regiment in Yerevan by a group of armed men, as well as the mass arrests and alleged arbitrary detention based on administrative procedure, ill-treatment and denial of fundamental legal guarantees, such as access to lawyers and doctors, notification of detention and violation of the three-day time limit for transferring persons deprived of liberty from a police station to a detention facility (arts. 12, 13 and 16). 21. The Committee reiterates its previous recommendation (see CAT/C/ARM/CO/3, para. 20) with regard to investigations into the 10 deaths that occurred as a result of excessive and indiscriminate use of force by police in March 2008. As regards other allegations of excessive use of force against protesters, ill-treatment and denial of fundamental legal guarantees, including during the protests of June 2015 and 17 to 31 July 2016, the State party should: (a) Ensure that prompt, impartial and effective investigations are undertaken into all such allegations, that the perpetrators are prosecuted and that the victims are provided with redress; (b) Ensure that all law enforcement officers receive systematic training on the use of force, especially in the context of demonstrations, and the employment of non-violent means and crowd control, and that the principles of necessity and proportionality are strictly adhered to in practice during the policing of demonstrations. Attacks on journalists 22. The Committee is concerned at reports that journalists had been subjected to violence, intimidation, arrest and detention and the destruction or confiscation of their equipment during the events of June 2015 and July 2016 referred to in paragraph 20 above. It notes that a small number of criminal proceedings were initiated, mainly for the “obstruction of lawful activities of journalists”, and that a few investigations are ongoing. The Committee is also concerned about the reported practice of initiating parallel criminal proceedings against journalists for perjury, non-compliance with the lawful orders of the police and violence against representatives of the authorities in retaliation for their reporting of police violence (arts. 2, 12, 13 and 16). 23. The Committee calls upon the State party to publicly condemn threats and attacks on journalists; ensure their protection, including against reprisals, and their safety; abstain from undue obstruction of their professional activities; investigate effectively all allegations of violence, intimidation and destruction of the property of journalists and sanction perpetrators with penalties commensurate with the gravity of their acts; and refrain from initiating criminal proceedings against journalists in retaliation for their reporting of police violence. Domestic violence 24. The Committee, while welcoming the measures taken to combat violence against women, including the establishment in 2013 of a separate division on the fight against domestic violence within the police, remains concerned (see CAT/C/ARM/CO/3, para. 18) that domestic violence is still prevalent and often goes unreported owing to entrenched gender stereotypes justifying such violence and the lack of due diligence on the part of law enforcement officials in pursuing cases. It is further concerned: (a) that cases of domestic 7
