There was confusion on Okunola Road in the Idimu area of Lagos State after suspected armed robbers unleashed mayhem.
A police inspector, who had just left a commercial bank in the area around 11.45am, was attacked and robbed by a three-man gang, which came on a motorcycle.
They reportedly shot the inspector in the jaw before dispossessing him of his money.
While the robbers were escaping from the scene, a police patrol team, attached to the Anti-Pipeline Vandalism Intelligence Unit, engaged the robbers in a shootout.
Two of the robbers were reportedly killed during the exchange, while a surviving member of the gang, identified as Gafaru Ismail, was arrested.
Two pistols were recovered from the gang.
The injured police inspector, who was not in uniform at the time of the attack, was reportedly rushed to a general hospital in the area, while the slain robbers and the suspect were taken to the Special Anti-Robbery Squad, Ikeja.
