The Enforcement Directorate has sought legal assistance from Singapore and Mauritius to take forward its probe in the alleged financial irregularities in the Indian Premier League tournament and its former chairman Lalit Modi.

Officials said the agency has initiated the "legal procedures" to obtain from a court two Letters Rogatories (overseas judicial requests) to be sent to the two countries as part of its probe in the alleged laundering of funds in awarding media rights of the money spinning cricket tournament in 2009.

An ED team from its Mumbai zonal office has also been sent to Singapore but officials indicated they are part of an investigating team probing another case under the Prevention of Money Laundering Act. However, it is understood, the team could gather some important leads in connection with this deal case where the ED has recently show caused, under foreign exchange violation laws, Modi and 13 other BCCI-Indian Premier League officials and other private entities.
