New Delhi/IBNS: The Enforcement Directorate (ED) on Tuesday raided the premises of Delhi Chief Minister Arvind Kejriwal's personal secretary and others linked to the ruling Aam Aadmi Party (AAP) in a case related to Delhi Jal Board, media reports said.

The ED raided 10 locations linked to Kejriwal's personal secretary Bibhav Kumar in connection with the case.

It is alleged that Delhi Jal Board chief engineer Jagdish Kumar Arora bypassed the contract to NKG Infrastructure Ltd. for the supply, installation, testing and commissioning of electromagnetic flow meters while the company failed to meet the technical eligibility criteria.

The ED probe, as Hindustan Times reported, found that the company secured the contract by submitting forged or false documents.

The latest heat on the city government and AAP came amid the ED's repeated summons to Kejriwal in connection with the Delhi liquor policy case.

The probe agency is investigating the Delhi excise policy which has handed over liquor shop licences to private players.

The Central Bureau of Investigation (CBI) alleges that liquor companies and middlemen were "actively involved in irregularities in the framing and implementation" of the excise policy.

Former Delhi Deputy Chief Minister and Kejriwal's colleague in the party, Manish Sisodia, is already in jail in the same case as the prime accused.
