The Senate on Tuesday mandated its standing Committee on Ethics, Privileges and Public Petitions to investigate the assault on a security guard, Clement Sargwak.
The assault was allegedly committed by the Chairman of the Code of Conduct Tribunal (CCT), Danladi Umar, at Banex Plaza, Wuse II, Abuja.
Mr Sagwak had petitioned the Senate through Istifanus Gyang (Plateau North).
President of the Senate Ahmad Lawan asked the Committee on Ethics and privileges headed by Ayo Akinyelure to investigate the matter and report back in four weeks.
The Senate investigation was premised on the fact that the petitioner has yet to seek redress in court.
Earlier presenting the petition at plenary, Mr Gyang said the petitioner was seeking justice, after being assaulted by the CCT judge, while carrying out his duty.
