We present new more sensitive high-resolution radio observations of
a compact BAL quasar, 1045+352, made with the EVN+MERLIN at 5 GHz.
They allowed us to trace the connection between the arcsecond
structure and the radio core of the quasar. The radio morphology of
1045+352 is dominated by a knotty jet showing several bends (Fig.1).
We discuss possible scenarios explaining
such complex morphology: galaxy merger, accretion disc instability,
precession of the jet and jet-cloud interactions.
It is possible that we are whitnessing in this source an ongoing
jet precession due to internal instabilities within the jet flow,
however, a dense environment detected in the submillimeter band
and an outflowing material suggested by the X-ray absorption
can strongly interact with the jet. It is difficult to
establish the orientation between the jet axis and the observer in
1045+352 because of the complex structure. Nevertheless taking into
account the most recent inner radio structure we conclude the radio
jet is oriented close to the line of sight which can mean that the
opening angle of the accretion disc wind can be large in this source.
We also suggest that there is no direct correlation between
jet-observer orientation and a possibility of observing BALs.
