Ezike said Otu Attang, who survived the February 22 attack and Chukwudi Iboko and Sunday Agbo, the deceased officers, have been recommended for promotion.
Four armed men had trailed a man to the bank in Owerri, and in the process, killed Chukwudi Iboko and another policeman.
In the gun battle, Iboko killed one of the robbers identified as Ikechukwu Okpara.
Ezike said the recommendation followed the huge sacrifice the three officers made to save the bank and its customers.
“The officers were gallant and showed serious commitment during the robbery attack. Nigeria Police Force cannot abandon them,” he said.
He said three of the suspected armed robbers, Ogbonna, Abiye Charles and Okechukwu Nwanegbo, who attacked the bank, had been arrested, adding that different types of arms were recovered from them.
