  We investigate the possibility to identify photon-gluon fusion (PGF) events
in polarised deep inelastic ep scattering, assuming the kinematics of the HERA
collider, by a pair of charged high p_t particles. In a Monte Carlo study we
find possible selection criteria and show the expected measurable asymmetries.
We discuss the sensitivity to $\Delta G(x)$ and compare the result to the one
obtained using di-jets to tag PGF events.
