A Greek newspaper has published what it says is the name of a British spy chief who was involved in the abduction and mistreatment of 28 Pakistani migrants.
Proto Thema said the name was that of a diplomat who was the Athens chief of Britain's intelligence service MI6.
It also named 15 Greek agents who it says were involved in the operation, which allegedly took place after the 7 July bombings in London.
The UK government has forbidden the media from naming the man.
The Greek intelligence agency earlier said it deplored the naming of the officers.
The British government previously described allegations of ill-treatment of migrants following the London bombings as "utter nonsense" and "farfetched".
Proto Thema said the swoop on the Pakistanis was a co-ordinated operation involving Greek and British intelligence services.
The Greek intelligence agency, EYP, condemned the newspaper for what it called "illegally endangering the safety of its agents in the field".
It is understood two of the Greek agents named in the article had to be recalled from operations in Kosovo.
The BBC's correspondent in Athens, Malcolm Brabant, said that in the past few weeks more details had emerged of the alleged mistreatment by Greek-speaking agents.
"One detainee has alleged that he had a gun placed in his mouth; one said he was beaten; and another claimed he saw a third detainee being beaten up," he said.
All 28 said they had hoods placed over their heads and some were held incommunicado for seven days.
