  We report finding high-velocity components in the H{\alpha} emission wings of
St 2-22 spectra, obtained in 2005. This discovery have encouraged us to start
the present study, aiming to show that this little studied object is a jet
producing symbiotic system. We used high-resolution optical and low-resolution
near infrared spectra, as well as available optical and infrared photometry, to
evaluate some of the physical parameters of the St 2-22 components and the
characteristics of the jets. The evaluated parameters of the components
confirmed that St 2-22 is a S-type symbiotic star. Our results demonstrate that
an unnoticed outburst of St 2-22, similar to those in classical symbiotics,
occurred in the first half of 2005. During the outburst, collimated, bipolar
jets were ejected by the hot component of St 2-22 with an average velocity of
about 1700 km/s.
