The National Assembly Complex is now under heavy security guard as protesters clashed over the ongoing probe of the Niger Delta Development Commission.

Both the Senate and the House of Representatives are investigating the alleged illegal spending and mismanagement by the Interim Management Committee of the NDDC under the supervision of the Minister of Niger Delta Affairs, Senator Godswill Akpabio.

While the group supporting the National Assembly probe is Emerging Leaders Forum of Nigeria, the group backing the NDDC and Akpabio against the probe is Niger Delta Development Initiative.

Security operatives had to separate the two groups.
