Abubakar gave the assurance in Abuja in an interview with newsmen shortly after the inauguration of 12 patrol vehicles for the Abuja-Kaduna Highway.
The News Agency of Nigeria (NAN) recalls that 49 police personnel and 10 operatives of the State Security Service (SSS) were killed at Alakyo Village in Nasawara State on May 7.
They were alleged to have been killed by members of the Ombatse cult from the ancestral shrine of the Eggon speaking people of Nasarawa State.
Abubakar vowed that nobody or group of persons operating under any name would kill the personnel of the force and go scot-free.
“Investigation is ongoing and the outcome of the investigation will be revealed to Nigerians at the most appropriate time.
“We cannot keep quiet to allow anybody in this country, whether individual or group of persons, under whatever canopy they call themselves, to kill officers of the police and go scot-free.
“There has never been speculation, we have always given the number out, that we lost 49 police officers,” he said.
Commenting on the closure of Wonderland Amusement Park and Amigo Supermarket, the I-G said the closure was part of measures to secure the nation.
“There is nothing new, security is security. You know what is happening in the country.
“We will go ahead to take any measure that deserves to be taken to ensure that Nigeria is safe and Nigerians are given safe and secured environment.
“We shall do everything humanly possible beyond reasoning to ensure that Nigeria is safe and our people are safe and secured no matter what it takes,” he said. (NAN)
