India's top investigation agency has raided houses owned by a former telecoms minister allegedly involved in a corruption scandal, reports say.
The Central Bureau of Investigation (CBI) conducted searches on Andimuthu Raja 's houses in Delhi and Madras.
Mr Raja quit last month, denying allegations that he had undersold mobile phone licences.
Parliament has been deadlocked after the government rejected a joint inquiry into the alleged scam.
The allegations against Mr Raja have been described by some analysts as the country's biggest-ever scandal - amounting to about $37bn (£23bn).
CBI officers have begun searching the homes of Mr Raja in connection with the alleged scam, a spokesman for the agency told Reuters news agency.
The homes of other former telecommunications ministry officials - including Mr Raja's former personal secretary RK Chandolia - have also been searched.
Mr Raja is accused of issuing 2G licences in 2008 on a "first-come, first-served" basis instead of auctioning them, costing the government billions of dollars in lost revenue. BBC News
