  We present the first deep photometry of a good candidate for a forming polar
ring galaxy at redshift z~0.05. This object, named FCSS J033710.0-354727, is a
background galaxy in the VST deep field of the Fornax cluster. The deep
exposures combined with the high angular resolution of the OmegaCAM at VST
allow us to carry out the first detailed photometric analysis for this system
in the g and i bands to derive the galaxy structure and colors. Results show
that the central object resembles a disk galaxy, surrounded by a ring-like
structure 2 times more extended than the central disk. The warped geometry and
the presence of bright knots observed along the polar direction, as well as the
several debris detected on the NW side with colors comparable to those of the
galaxy, suggest that the polar structure is still forming. We argue that the
wide polar ring/disk is the result of the ongoing disruption of a companion
galaxy in the potential of the central object, which is 2-3 times more massive
than the accreting galaxy.
