Chandigarh, April 6 (IANS): A senior officer of the Enforcement Directorate (ED), who is probing the sensitive multi-million-rupee synthetic drugs case, on Monday approached the Punjab and Haryana High Court opposing his recent transfer to Kolkata.

ED assistant director Niranjan Singh was transferred from Jalandhar to Kolkata within days after he questioned Punjab's powerful Revenue Minister Bikram Singh Majithia, the brother of union minister Harsimrat Badal and brother-in-law of Deputy Chief Minister Sukhbir Singh Badal.

Majithia was questioned in December last year by the ED following allegations of his links with three Non-Resident Indians (NRIs) who were being investigated for money laundering connected to a Rs.6,000 crore international synthetic drugs racket busted by Punjab Police in 2013.

The high court had in January this year stayed the transfer of Niranjan Singh on a petition filed by a lawyer here.

During hearing of the matter on Monday, advocate Anupam Gupta, appearing for Niranjan Singh, pleaded to become party in the case. He opposed the ED official's transfer.

The ED is under union Finance Minister Arun Jaitley, who had made Majithia his campaign in-charge during the parliamentary elections in Amritsar Lok Sabha constituency, which Jaitley had contested and lost.
