Some residents of Anambra State have said they still receive threats from persons claiming to be members of the Indigenous People of Biafra (IPOB) to stay at home on Mondays.
IPOB had called off the directive, which was declared to protest the detention of its leader Nnamdi Kanu.
Despite the cancellation, major markets have remained shut on Mondays in the Southeast.
On Monday banks, markets and shops in Onitsha and Nnewi were shut.
A market leader said: “We continue to receive threats from unknown persons.
“Nobody wants to risk his or her life for nothing. One of our colleagues was killed almost a month ago for announcing that people should shun the order.”
One of such threat messages reads: “You are flouting our order and what it means is that you are not an Igbo person.
“We’re monitoring you and if you don’t refrain from your hide and seek game, you will soon regret it.”
Reacting to a similar letter in the past, IPOB spokesman, Emma Powerful, said: “We don’t know anything about the letter to market leaders. We issued a statement that sit-at-home has been suspended.”
IPOB had threatened to hunt down “impostors” who it claimed were enforcing the cancelled exercise, but the Army accused IPOB of deception, saying its members were still enforcing the directive.
