Opposition Hayastan alliance member Narek Mantashyan has been taken to hospital from prison, his lawyer Alexander Kochubaev said on social media.

He was hospitalized late on Friday due to heart issues caused by elevated blood glucose levels, the lawyer said.

“The current authorities have come to realize that they can no longer keep people in prison on trumped-up charges and are making every effort to cause their death,” Kochubaev wrote.

"Judge Karen Farkhoyan never bothered to hold an emergency hearing in a month to consider the motion over the incompatibility of Mantashyan's health condition with arrest, while the state has clearly failed in its function of ensuring his health," the lawyer said.

Narek Mantashyan is accused of involvement in mass riots in Yerevan on 10 November 2020.
