Hoodlums, numbering over 30, disrupted proceedings in the hearing of a suit into the disputed ward, local government and state congresses of the All Progressive Congress (APC) at the Bayelsa State High Court.
The claimant, Alex Blackson and his brother, Osom Blackson, were injured during the stampede in the court room, while the presiding Judge, Justice Nayai Aganaba, was stoned.
The Judge was later whisked to safety by his police orderly.
Most of the lawyers were chased out, while those who came with the claimant were brutalised.
The hoodlums were said to have been provoked over the alleged insistence of Justice Aganaba to hear the suit filed by Alex Blackson, seeking the order to set aside the disputed congresses of the APC held last year.
There was also sporadic shooting at the State Secretariat of the APC following the attempts by policemen to arrest some chieftains of the party over their alleged involvement in the court invasion.
