Iraqi officials now say Saddam Hussein's former top deputy was not arrested as had been announced Sunday.
The Interior Ministry says Monday medical tests indicate that a person arrested during a raid Sunday near Tikrit is not Izzat Ibrahim al-Douri.
The statement says the man arrested was a relative of the former aide who was also wanted by authorities, but was not a top former official.
Iraqi officials announced Sunday that Saddam's top aide had been captured by Iraqi forces near Tikrit, but later the defense minister (Hazem Shaalan) said the report was "baseless."
Ibrahim al-Douri is the most wanted member of the ousted dictatorship still at large, and there is a $10-million reward for his capture.
