New Delhi: The Enforcement Directorate on Tuesday said it has started an investigation against underworld don Dawood Ibrahim's brother Iqbal Ibrahim Kaskar, and three others for extortion and illegal transfer of property.
"ED begins investigation against Kaskar, Israr Z. Saiyyad, Mumtaz A. Shaikh and others for extortion and illegal transfer of property," an ED official said here.
Saiyyad and Shaikh are associates of Kaskar.
The financial probe agency's action comes after Iqbal was arrested in Mumbai last week for allegedly threatening a builder using Dawood's name and had demanded four flats and Rs 30 lakh cash.
The agency officials also said that they would soon grill Kaskar and his two associates.
The official further said that after investigation under the prevention of money laundering act, the agency might also attach the properties of absconding fugitive mafia.
Iqbal Kaskar lives in India after being deported from the United Arab Emirates in 2003.
