Armed robbers attacked a bullion van transporting money to a bank at Idi-Ape in Ibadan, in Oyo state, allegedly killing three police officers and four others.
The armed robbers were said to have dressed in police uniform, trailing the van to Idi-Ape and, tried unsuccessfully to intercept the bullion van at the area.
It would be recalled that a similar robbery incident happened in 2008 where scores were brutally killed.
The robbers allegedly fired several shots at the escort van in a bid to intercept the van and cart away the money.
Unconfirmed report said the robbers were not able to loot the bullion van as the driver managed to escape with the van.
The police command launched a manhunt for the fleeing robbers, with the assurance that they would be arrested.
The state Police Public Relations Officer (PPRO), Adewale Osifeso is yet to state an official position on the matter.
