The Abia government has raised the alarm over alleged plots to attack key locations in the state.
In a statement on Friday, John Okiyi Kalu, the commissioner for information, said security agencies have been placed on “high alert”.
The commissioner said the identity of those behind the planned attacks is yet to be ascertained.
He urged residents of the state to be vigilant and ensure they return home before the curfew hours.
The statement read: “Abia State Government has uncovered plots by yet to be properly identified hoodlums to attack some key locations within the state soon.
“Security agencies in the state have been fully mobilized and placed on high alert to thwart the planned attack and bring those concerned to justice swiftly.
“We wish to advise members of the public to be extra vigilant, ensure they are at home before the curfew hours of 8pm to 6am as well as monitor the activities of their neighbours.
“Parents and guardians are also strongly advised to ensure that their children and wards are securely at home and not in anyway associated with the hoodlums some of whom are said to be coming from outside the state.
“Law abiding citizens are encouraged to go about their normal duties but ensure they return home before 6pm to avoid the rush associated with movement before the onset of curfew time.
“While we remain confident that the security architecture within the state is robust enough to prevent the planned attack and/or bring those involved in the plot swiftly to justice, the State Government led by Dr Okezie Ikpeazu will not spare any resource in ensuring the protection of law abiding citizens.”
The state government had on April 5 imposed a curfew on Umuahia and Aba metropolis, citing security reports received from multiple sources.
