IRAS 00521 - 7054 is the first Seyfert 2 in which the presence of an extremely large Fe K \alpha line has been claimed .
We report here on the analysis of a 100 ks Suzaku observation of the source .
We confirm the existence of a very strong excess over the power-law X-ray continuum at E \sim 6 keV ( EW \simeq 800 eV ) , extending down to \sim 4.5 keV , and found that the X-ray spectrum of the source can be explained by two different models .
i ) An absorption scenario , in which the X-ray source is obscured by two fully-covering ionized absorbers , with a strong reflection component from neutral material ( R \sim 1.7 ) , a black body component and four narrow Gaussian lines ( corresponding to Fe K \alpha , Fe K \beta , Fe xxv and Fe xxvi ) .
ii ) A reflection scenario , in which the X-ray spectrum is dominated by an obscured ( \log N _ { H } \sim 22.9 ) blurred reflection produced in an ionized disk around a rotating supermassive black hole with a spin of a \geq 0.73 , and affected by light-bending ( R \sim 2.7 ) , plus two narrow Gaussian lines ( corresponding to Fe K \alpha and Fe K \beta ) .
The narrow Fe K \alpha and K \beta lines are consistent with being produced by ionized iron , and in particular by Fe xiv –Fe xvi and Fe xii –Fe xvi for the absorption and reflection scenario , respectively .
While the X-ray continuum varies significantly during the observation , the intensity of the broad feature appears to be constant , in agreement with both the absorption and reflection scenarios .
For both scenarios we obtained a steep power-law emission ( \Gamma \sim 2.2 - 2.3 ) , and we speculate that the source might be an obscured narrow-line Seyfert 1 .
