  Extreme high-frequency peaked BL Lacs (EHBLs) are characterized by a
synchrotron peak frequency exceeding $10^{17}$ Hz and a second peak that can be
in the energy range of few GeVs to several TeVs. The MAGIC telescopes detected
multi-TeV gamma-rays on April 19, 2018 for the first time from the EHBL PGC
2402248 which was simultaneously observed in multiwavelength by several other
instruments. The broad band spectral energy distribution of the source is
conventionally modelled using the leptonic and the hadronic models. Due to the
success of the photohadronic model in interpreting the enigmatic very
high-energy (VHE) flaring events from many high-energy blazars, we extend this
model to explain the VHE events from PGC 2402248 observed by MAGIC telescopes
and compare our results with other models. We conclude that the photohadronic
fits are comparable and even fare better than most other models. Furthermore,
we show that the spectrum is not hard and is in a low emission state. The
estimated bulk Lorentz factor for this flaring event is found to be $\lesssim
34$.
