The House of Representatives Committee on Ecology, has begun investigation of states and agencies over money released to them under the Ecological Fund.
The committee is carrying out the probe after paying oversight visit to some states ravaged by floods.

According to the committee, only about 10 states, including Ogun, Enugu, Plateau, Kwara, Imo, Niger, Ondo, Borno and Jigawa, honoured the invitation extended to the 36 states of the federation.
