The deceased, who goes by the name, Inspector Ahmed, alongside his colleagues, was returning to Damaturu after an official assignment in Maiduguri.
It was gathered that they met the Boko Haram insurgents who dressed in military uniform at a roadblock.
The gallant Police Officer, it was learnt, approached the terrorists to inquire from them the reason for blocking the high way.
The insurgents outrightly shot Inspector Ahmed and subsequently beheaded him, while the remaining police escorts ran back without any attempt to rescue their colleague.
A police source who does not want his name to be published confirmed the killing and the beheading of the Inspector.
The source described the incident as unfortunate, saying the Inspector passed away when the police command in the state needed him the most.
