A Spanish politician today angrily rejected an apology for the FBI using his picture to create a poster showing what Osama bin Laden might look like today.
Gaspar Llamazares, of Spain's communist-run United Left party, demanded the US investigate the incident and take appropriate action.
"Apologies are not enough," he said after the US ambassador apologised via Spain's interior minister yesterday.
"I want a thorough investigation into this disgraceful case, which not only causes concern but also worry and indignation over the behaviour of the FBI," he said, adding that he did not rule out legal action.
The FBI used parts of a photo of Mr Llamazares taken from Google Images to create a digitally modified image of the al Qaida leader for a new wanted poster, which appeared on the State Department website and offered a reward of up to 25 million dollars.
The FBI said the forensic artist had been unable to find suitable features among the reference photographs of bin Laden, and in part used features from a photograph found online.
The FBI has since removed the doctored photo of bin Laden from the site, but Mr Llamazares said he wanted guarantees that the images were not still in the hands of intelligence services at airports or other places abroad.
He said it bothered him to think what would have happened if the FBI had used the photo of an ordinary person, and not a public figure able to draw attention to the matter.
"Most likely an unknown citizen on stepping into an airport would have received a good fright, if not something worse," the politician said. "If this is how security against terrorism is guaranteed, whose hands are we in?"
Mr Llamazares, known as an anti-war activist in Spain, said he also wanted to know if the FBI had a habit of keeping files on left wing politicians in the US, Europe, Latin American or elsewhere. He said he doubted the FBI had found his photo by chance on the internet.
Mr Llamazares said the FBI used images of his hair to construct a photograph of another alleged terrorist, Atiyah Abd al-Rahman, of Libya.
His picture originally appeared on posters for his 2004 parliamentary election campaign.
