Security operatives, including members of the Joint Military Task Force, were reportedly overwhelmed by the attack.
The brazen attack led to raids on three major banks in the township namely First Bank, GuarantyTrust and Access bank.
A dozen persons were reportedly killed, and several others injured in the attack as the robbers freely used dynamites to blast open large bank doors and strongrooms.
Report says the attackers razed a police station and shot some police officers in the attack.
