  We perform a weak lensing analysis on a previously reported dark-lens
candidate on STIS Parallel data (Miralles et al. 2002). New VLT-data indicate
that the reported signal originates from a small number of galaxies
tangentially aligned towards the center of the STIS field but no signature for
an extended mass distribution is found. We argue that we should be able to
detect a massive cluster ($M\geq 3.2\times 10^{14}M_{\odot}$) through its
lensing signal up to a redshift of $z\approx 0.6$ with our data. Also the
double image hypothesis of two galaxies with very similar morphologies in the
STIS data is ruled out with colour information.
