New Delhi, June 9 (IANS): The newly-appointed Anti-Corruption Branch (ACB) chief, M.K. Meena, who was earlier in the day directed by the Delhi government to go back to Delhi Police, said on Tuesday that he is still holding the charge as the row over the appointment raged on.

"I don't want to comment on order (of Delhi government)...Our action will be impartial and as per law. I have orders of competent authorities and I am holding the charge," he told reporters here.

Earlier in the day, the Delhi government directed Meena to return to Delhi Police, the organisation where he was joint commissioner earlier. The city government also slammed the shifting of Meena by Lt. Governor Najeeb Jung, terming it a "conspiracy".

"He has been told to go back to Delhi Police since there is no post of joint commissioner of police in the ACB," a government official told IANS.

Meena was appointed the ACB chief on Monday. The action drew flak from the AAP government.

"What is the conspiracy by creating a new post of joint commissioner in the ACB and appointing your favourite officers?" Deputy Chief Minister Manish Sisodia tweeted soon after the controversial appointment.

"Has the appointment been done because of the fear of CNG case being probed by the ACB?" he asked.

Before he appointed Meena, Jung rejected the Aam Aadmi Party government's induction of Bihar Police officials in the ACB, saying the wing came under his administrative control.

Meena replaced S.S. Yadav as the ACB head. Jung also transferred seven police inspectors to the ACB.

The development comes as the AAP government and Jung are embroiled in a battle over a host of issues related to the national capital.
