Former civil aviation minister and NCP leader Praful Patel appeared before the Enforcement Directorate for a second day Tuesday for questioning in connection with a money laundering probe related to losses suffered by Air India as part of an alleged multi-crore aviation scam, officials said. Patel appeared before the agency at its headquarter here in Khan Market around 10.00 am. On Monday also, he was questioned by the agency for about right hours. The investigating officer of the case recorded Patel’s statement under the Prevention of Money Laundering Act (PMLA) on Monday and the former Union cabinet minister of the UPA government was understood to have “cooperated” with the agency. The Rajya Sabha MP was asked to appear again on Tuesday as the questioning and recording of his statement has to continue, officials said.
