  A systematic study of thermomagnetic irreversibility CoS$_{1.76}$Se$_{0.24}$
has been carried out. Our study shows that the resistivity at low temperature
can be tuned by cooling in different magnetic fields and the critical field
required for paramagnetic (PM) to ferromagnetic (FM) transition varies
non-monotonically with temperature. The field induced PM to FM transition
results in giant positive magnetoresistance (MR) of about 160\% at 5 K.
Measurements under CHUF (cooling and heating in unequal magnetic field)
protocol show reentrant transition on warming under higher magnetic field (than
that applied during cooling). It indicates that the glass like behaviour in
this system can be explained in the framework of the kinetic arrest of first
order transition. Among the growing list of diverse system showing glass like
arrested magnetic states, the present system is the first example where,
kinetic arrest is observed for a disordered (here PM) to ordered (here FM)
first order transition.
