Former Haryana MLA Dilbag Singh and his aide Kulwinder Singh were arrested by the Enforcement Directorate (ED) on Monday in an alleged illegal mining-linked money laundering investigation, official sources said.

Singh is a former legislator of the Indian National Lok Dal (INLD) from the Yamuna Nagar assembly seat. The agency raided him and the Congress MLA from Sonipat Surender Panwar on January 4 and the searches ended after five days on Monday.
