But the Police Public Relations Officer, Mr. Andrew Enwerem, could not confirm the casualty as he is out of the state.
The News Agency of Nigeria reports that the situation escalated when one of the protesters, a young man, was hit and killed by a stray bullet fired by security operatives deployed to maintain order in the melee which ensued after the demolition.
Following the death of the protester, Owerri natives proceeded to set fire to the property belonging to some residents.
This led to a fight between the residents and those protesters resulting in the death of two others.
Governor Rochas Okorocha of Imo state had issued an evacuation order to the traders advising them to relocate to a new site to make way for development at the market site.
The efforts were resisted by the natives of the area who fought the relocation of the market by the state government.
However, the market was demolished in the middle of the night by bulldozers already stationed at the scene despite the efforts of the natives.
Military and police personnel have been deployed in Owerri to forestall further breakdown of law and order.
