The IceCube Collaboration initially reported the detection of 37extraterrestrial neutrinos in the TeV - PeV energy range. The reconstructedneutrino events were obtained during three consecutive years of data taking,from 2010 to 2013. Although these events have been discussed to have anextragalactic origin, they have not been correlated to any known source.Recently, the IceCube Collaboration reported a neutrino-induced muon event withenergy of $2.6\pm0.3$ PeV which corresponds to the highest event ever detected.Neither the reconstructed direction of this event (J2000.0), detected on June11 2014 at R.A.=110$^\circ$.34, Dec.=11$^\circ$.48 matches with any familiarsource. Long gamma-ray bursts (lGRBs) are usually associated with the corecollapse of massive stars leading relativistic-collimated jets inside starswith high-energy neutrino production. These neutrinos have been linked to the37 events previously detected by IceCube experiment. In this work, we explorethe conditions and values of parameters so that the highest neutrino recentlydetected could be generated by proton-photon and proton-hadron interactions atinternal shocks inside lGRB progenitor star and then detected in IceCubeexperiment. Considering that internal shocks take place in a relativisticcollimated jet, whose (half) opening angle is $\theta_0\sim$ 0.1, we found thatlGRBs with total luminosity $L\lesssim 10^{48}$ erg/s and internal shocks onthe surface of progenitors such as Wolf-Rayet (WR) and blue super giant (BSG)stars favor this multi-PeV neutrino production, although this neutrino could beassociated to $L\sim 10^{50.5}$ ($\sim 10^{50}$) erg/s provided that theinternal shocks occur at $\sim 10^9$ ($\sim 10^{10.2}$) cm for a WR (BSG).

Could a multi-PeV neutrino event have as origin the internal shocks inside the GRB progenitor star?
