  Let $I$ and $J$ be two ideals of a commutative Noetherian ring $R$ and $M$ be
an $R$-module of dimension $d$. If $R$ is a complete local ring and $M$ is
finite, then attached prime ideals of $H^{d-1}_{I,J}(M)$ are computed by means
of the concept of co-localization. Also, we illustrate the attached prime
ideals of $H^{t}_{I,J}(M)$ on a non-local ring $R$, for $t= \dim M$ and $t=
cd(I,J,M)$.
