Officers will now be required to wear proper identification badges, according to an announcement signed by the Chief of the Hellenic Police (ELAS), published in the Government Gazette.
ELAS said it would begin the practice of the badges on the uniforms of officers and the helmets of riot police who were singled out for aggression.
Any unauthorised badge will constitute a disciplinary offence.
The social unrest over police brutality comes in the midst of the ongoing coronavirus pandemic.
Last month, an officer that beat a citizen with his baton (during Covid-19 compliance checks) in the southern suburb of Nea Smyrni, was suspended from the force.
Greek Prime Minister Kyriakos Mitsotakis called for restraint.
“The sad images of violence we all saw tonight in Athens must be the last ones. And the life of one of our fellow citizens, a young policeman who was in danger, should awaken us,” Mitsotakis said.
“I will not allow anyone to divide us.”
