An Algerian arrested following an international probe into an alleged plot to murder a Swedish cartoonist has been refused bail.
Ali Charafe Damache was among seven men and women people arrested by Irish anti-terrorist units acting on intelligence from the CIA, FBI and European agencies.
The 44-year-old was later charged with an unrelated offence of sending a message by phone to a third party, which was of menacing character, on January 9, 2010.
Prosecutors who opposed bail told Dublin's High Court investigators were not sure of the accused's true identity as he travelled to Ireland on false documents in 2000, had previously used other names, had Algerian and Irish passports and recently moved address.
Mr Justice Paul Butler - who refused bail - agreed there was a real doubt about his identity and questioned Damache's propensity to use false documents.
"He's a very real risk," said the judge.
"His affidavit is highly questionable."
Damache was held after investigations into a conspiracy to kill Lars Vilks, whose controversial depictions of the prophet Mohammed with the body of a dog were printed in a newspaper in Sweden in 2007.
