This happened only a day after hoodlums fled after torching the Orlu High Court.
The Owerri High Court is housed at the Magistrate's Court, which is situated in the centre of the state capital.
The suspects came with explosives and targeted a portion of the facility's roof, a source told our correspondent.
While our correspondent was unable to determine the full amount of the fire damage, he did hear that critical court records and files, including files, had been burned.
The source said, “Hoodlums have razed part of the Owerri Magistrate’s Court located at Owerri-Orlu Road. It happened today ( Sunday). This is very unfortunate.”
Our correspondent who visited the scene on Sunday afternoon observed that smokes were oozing out from part of the court building that was burnt.
When contacted, the police spokesperson for the state command, Micheal Abattam, confirmed the incident and disclosed that the fire had been put out.
He also informed that the command had begun an investigation with a view to arresting the culprits.
