New Delhi, Dec 21 (IANS) A Central Bureau of Investigation (CBI) team Tuesday reached corporate lobbyist Niira Radia’s house in Delhi to question her further in the 2G spectrum scam.

The team of sleuths was accompanied by women officers for the first formal questioning of Radia in irregularities in the allocation of 2G spectrum.

CBI officials Monday questioned former Telecom Regulatory Authority of India (TRAI) chief Pradeep Baijal, whose premises were raided by the CBI last week along with Radia, former communications minister A. Raja and others linked to him.

Baijal was the TRAI boss between 2004 and 2008. He joined Radia’s firm in 2009. The Enforcement Directorate too has grilled Radia about her role in the spectrum allocation.
