The man’s story echoes complaints from human-rights groups that Greek authorities often expel asylum seekers indiscriminately and violently.
ATHENS — For years, Greek officials have denied complaints from human rights groups that the country’s border agents have brutalized migrants and forcibly pushed them back into Turkey. They have dismissed the allegations as fake news or Turkish propaganda.
Now a single case may force a reckoning.
A European Union interpreter says that in September, Greek border guards mistook him for an asylum seeker, assaulted him and then forced him across the border into Turkey alongside dozens of migrants.
His allegation is particularly problematic for Greek officials because he is a legal European Union resident employed by the E.U. border agency, Frontex. And he has turned over evidence to the agency to support his claims of abuse, according to European officials dealing with his case.
