Amnesty International said on Thursday that it had found a culture of impunity and abuse within the Greek police.

It also criticised the police for inadequately responding to hate crimes and attacks by far-right groups on migrants and protesters.

Another group created to monitor hate crimes also criticised the police in a separate report.

The Racist Violence Reporting Network concluded that hate crimes by Greek police increased last year, despite a “significant decrease” in such attacks following a judicial crackdown on the fascist Golden Dawn party.

“Under no circumstances should one get the impression that Greece has adequately dealt with the problem of racist violence,” the network said.

Amnesty called on the government to fix “a range of failures undermining public confidence and generating a host of human rights violations.”

It said it had documented allegations of torture or ill-treatment during arrest and detention.
