The Prosecutor General's Office of Armenia is investigating a video which shows a police officer hitting an opposition protester in the head and face in Yerevan on Monday, its spokeswoman Arevik Khachatryan told Panorama.am.

The video went viral on social media, drawing strong condemnation from people.

The man was taking part in mass acts of civil disobedience launched by the Armenian opposition on Monday morning in a bid to oust Nikol Pashinyan and his cabinet.

The footage clearly shows one of the police officers repeatedly hitting him in the face and head while detaining him. The policeman is taken away by other protesters.
