In the case of illegal mining, the ED can soon issue notice to these MLAs and call for investigation. This case is directly related to Captain Amarinder Singh's son Raninder.

Abdullah, the former Chief Minister of Jammu and Kashmir, was questioned by the ED for nearly six hours. Abdullah said after questioning on Monday that he was not worried and would cooperate in the investigation.

The Enforcement Directorate has attached assets worth Rs 5 crore of former Uttar Pradesh cabinet minister Rangnath Mishra in connection with a money laundering case, the agency said on Saturday. Mishra was the minister for secondary education and home in the 2007-11 Bahujan Samaj Party (BSP) government headed by the then Uttar Pradesh chief minister Mayawati.

The request was made after Solicitor General Tushar Mehta, appearing for the agencies, sought more time to complete the probe.

The ED officials said Gupta's role in the case came to light on the basis of disclosures made by Rajiv Saxena, who has recently turned approver in the case after he was deported from the UAE and arrested by the Enforcement Directorate (ED) here.

A court has given Robert Vadra immunity from arrest till February 16, but also asked that he join the investigation.

Robert, who was grilled for six long hours on Wednesday, denied owning a series of properties in London and having any business ties with arms dealer Sanjay Bhandari and his cousin Sumit Chaddha.
