Gunmen on Wednesday attacked a bullion van in Ebonyi State, killing four policemen escorting the vehicle and injuring two.
The robbers were said to have intercepted the bullion van, which was transporting money from Enugu to Abakaliki, at Ezzamgbo just a, in Ohaukwu local government area.
In a bid to succeed in their evil venture, the hoodlums first fired at the escort van carrying the policemen and in the process killed four, while two sustained injuries.
The State Commissioner of Police, Philip Maku, who confirmed the incident in Abakaliki, said the robbers trailed the van from Enugu State.
Maku added that the robbers were not able to steal the money as the driver managed to manouvre the van out of the scene of crime.
He explained that the robbers damaged one of the tyres of the bullion van, but the driver was able to escape with the van, adding that they could not chase the van because the driver headed towards a military checkpoint ahead.
The Ebonyi CP said the two injured policemen had been taken to hospital for treatment, while the bodies of those killed had been deposited at the mortuary.
Maku said the police had launched a manhunt for the fleeing robbers.
