  We study a model in $d = 2 + 1$ space-time dimensions with two sectors. One
of them, which can be considered as the visible sector, contains just a $U(1)$
gauge field which acts as a probe for the other (hidden) sector, given by a
second $U(1)$ gauge field and massive scalar and Dirac fermions. Covariant
derivatives of these matter fields and a BF gauge mixing term couple the two
sectors. Integration over fermion fields leads to an effective theory with
Chern-Simons terms that support vortex like solutions in both sectors even if
originally there was no symmetry breaking Higgs scalar in the visible sector.
We study numerically the solutions which correspond to electrically charged
magnetic vortices except for a critical value of the BF coupling constant at
which solely purely magnetic vortices exist.
