Arvind Kejriwal, today directed the Anti-Corruption Branch to lodge an FIR in the Rs 90-crore street light project for the 2010 Commonwealth Games in which a panel headed by a former CAG had indicted the then Chief Minister Sheila Dikshit.

After a Cabinet meeting, senior Minister Manish Sisodia said the ACB has been told to conduct a thorough probe into the scam as there have been "strong findings" in it by CAG and Shunglu Committee.

"The ACB has been directed to conduct an independent and thorough investigation and take action. ACB will file FIR in the case. Our motive is not to target a particular person," Sisodia said.

Registration of an FIR is the first step in the filing of formal charges. Today's move was bound to needle its ally Congress.
