Seven people, including a policeman, were reportedly killed during the robbery.
Security operatives said they had arrested a suspect.
Akeredolu spoke yesterday when he visited the Alani of Idoani, Oba Olufemi Olutoye, at his palace.
Represented by his deputy, Agboola Ajayi, the governor described the incident as unfortunate but urged security agents to fish out the perpetrators.
Akeredolu assured the people that his administration would partner security agencies to tighten security.
He urged residents to assist the security operatives by giving them information, to reduce crimes.
Oba Olutoye said the hoodlums also entered his palace by damaging the entrance door, “but their efforts eventually became fruitless.”
He appealed to the government to assist the bereaved families.
Due to the robbery incident, economic activities at the neighbouring Akoko area were yesterday paralysed as commercial banks in the four local governments, especially in Ikare-Akoko, were shut down.
Many people, who came for transactions, returned home without achieving their aim.
