  We have analyzed the phase space distribution of a sample of about 900
non--kinematically selected low metallicity stars in the solar vicinity. The
stars primarily represent the thick disk and halo populations of the Milky Way.
We aim to identify overdensely populated regions in phase space, which we
interpret as signatures of star streams passing close to the Sun. The search
was conducted in a space constructed from the angular momenta and
eccentricities of the stellar orbits. Besides recovering all well known star
streams in the thick disk, we isolated four statistically significant phase
space overdensities amongst halo stars. One of them is associated with a
previously known halo star stream, but three of them are novel features, which
we propose be also considered as genuine halo streams.
