IRAS 00521$-$7054 is the first Seyfert 2 in which the presence of anextremely large Fe K$\alpha$ line has been claimed. We report here on theanalysis of a 100 ks Suzaku observation of the source. We confirm the existenceof a very strong excess over the power-law X-ray continuum at $E\sim6$ keV($EW\simeq 800$ eV), extending down to $\sim 4.5$ keV, and found that the X-rayspectrum of the source can be explained by two different models. i) Anabsorption scenario, in which the X-ray source is obscured by twofully-covering ionized absorbers, with a strong reflection component fromneutral material ($R\sim 1.7$), a black body component and four narrow Gaussianlines (corresponding to Fe K$\alpha$, Fe K$\beta$, Fe xxv and Fe xxvi). ii) Areflection scenario, in which the X-ray spectrum is dominated by an obscured($\log N_{\rm\,H}\sim 22.9$) blurred reflection produced in an ionized diskaround a rotating supermassive black hole with a spin of $a \geq 0.73$, andaffected 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$\alpha$ andK$\beta$ lines are consistent with being produced by ionized iron, and inparticular by Fe xiv-Fe xvi and Fe xii-Fe xvi for the absorption and reflectionscenario, respectively. While the X-ray continuum varies significantly duringthe observation, the intensity of the broad feature appears to be constant, inagreement with both the absorption and reflection scenarios. For both scenarioswe obtained a steep power-law emission ($\Gamma\sim 2.2-2.3$), and we speculatethat the source might be an obscured narrow-line Seyfert 1.
