Union minister Piyush Goyal on Thursday said the ED launched a probe against NCP leader Praful Patel after his signatures were found on the documents which were also signed by the wife of gangster Iqbal Mirchi. The Enforcement Directorate has summoned Patel on October 18 in connection with a probe into alleged illegal assets of Mirchi, who was an aide of fugitive gangster Dawood Ibrahim.

"The ED has some documents with signatures of Patel and Hazra Iqbal Memon (Mirchi's wife). The NCP has a track record of legendary corruption cases, hence the state should be worried about it," Goyal told reporters here. Iqbal Mirchi, a drug lord and an accused in the 1993 Mumbai serial blasts case, died in London some years back. The agency is expected to record Patel's statement under the Prevention of Money Laundering Act regarding a deal between a real estate company promoted by Patel and his wife, and Hazra Memon.
