NEW DELHI, MAY 17: The Delhi High Court today asked the Centre and Delhi Government to spell out their stand on a petition seeking CBI probe into model Jessica Lal murder case.A division bench comprising Justice Anil Dev Singh and Justice Mukul Mudgal issued the notices to Ministry of Home Affairs (MHA) and chief secretary to Delhi Government to file replies by May 21.The notices were issued on a criminal writ petition by a non-governmental organisation (NGO) - Bhrashtachar Virodhi Morcha (BVM) which alleged that Delhi police was not able to investigate the matter properly due to influence of higher ups.``Delhi police investigation uptil now is very poor and is giving an impression to the general public that the law is very poor and weak for big persons,'' the plea moved by advocates Mohammed Sajjid and Arun Kaushal said.The reports published in the media about the ``conduct of police officers clearly shows that a fair investigation is not possible.'' The petition said.It said the police officers probing the case were not in a position to take a ``bold investigation for reason that officers of higher rank are involved.''The police, apart from former joint commissioner of police YS Dadwal, was not yet able to release the names of three other senior officers who were allegedly present at socialite Bina Ramani's ``illegal'' Tamarind Court restaurant on the day Jessica Lal was shot dead.The petitioner said CBI investigation into the case also became necessary in view of Bina Ramani and her family members' foreign citizenship.The petition said the present case was not only a ``mystery'' of the murder of a model but could ``definitely disclose a dangerous nexus between the economic mafias causing irreparable loss to the nation by misusing powers and positions of high officials to achieve their ulterior motives''.``Because the names of top government officials (those present at the party on April 30) are yet to be revealed, the powerful officers are trying to suppress, humiliate and shut down the subordinate officers investigating the case,'' the petitioner alleged.Meanwhile, anticipatory bail petition of Jantantarik Bahujan Samaj Party (JBSP) leader DP Yadav's son Vikas Yadav was today dismissed as ``withdrawn'' by a sessions court.Vikas Yadav, who is sought by the police for allegedly helping Jessica Lal murder case main accused Manu Sharma, had moved anticipatory bail petition on Friday.His counsel today told the court that he would prefer to withdraw the plea following a writ petition in the High Court for CBI probe into the case. The sessions court subsequently dismissed the petition.
