The Supreme Court has restrained the Centre from taking any immediate action against Enforcement Directorate official Rajeshwar Singh, following some complaints lodged against him. <br/><br/>Singh is probing the multi-crore rupees Aircel-Maxis case and the 2G spectrum scam. <br/><br/>The court's direction came after Singh alleged conspiracy over filing of frivolous anonymous complaints against him with the Revenue Secretary saying these were being entertained by the ED. <br/><br/>He said such complaints were filed after the recent attachment of property worth one crore Rs. 16 lakh of the accused in the Aircel-Maxis case. <br/><br/>The court issued notices to the CBI, ED and the Department of Telecom and sought their responses in three weeks. <br/><br/>The court ruled that no action should be taken against Mr Singh till the pendency of his plea.
