  The 1ES 1959+650 is a high-peaked BL Lacertae object. On 4th of June, 2002,
it exhibited a strong TeV flare without any low energy counterpart, providing
for the first time an example of an orphan flare from a blazar. Observation of
this orphan flare is in striking disagreement with the predictions of the
leptonic models thus challenging the conventional synchrotron self-Compton
(SSC) interpretation of the TeV emission. Here we propose that, the low energy
tail of the SSC photons in the blazar jet serve as the target for the
Fermi-accelerated high energy protons of energy . 100 TeV, within the jet to
produce the TeV photons through the decay of neutral pions from the delta
resonance. Our model explains very nicely the observed TeV flux from this
orphan flare and we also estimate the high energy neutrino flux from this
flaring event.
