The Enforcement Directorate, ED, today issued fresh summons to Himachal Pradesh Chief Minister Virbhadra Singh after he failed to appear before it in a money laundering probe case. <br/><br/>The ED on Monday attached a farmhouse in Delhi belonging to Mr Singh's family. The farmhouse, worth around 27 crore rupees, was attached under the Prevention of Money Laundering Act (PMLA).<br/><br/>The move comes days after the Central Bureau of Investigation (CBI) filed a chargesheet against Mr Singh accusing him of accumulating disproportionate assets during the time he served as a union minister in the UPA regime. <br/><br/>Last week, the CBI had filed a chargesheet against Virbhadra Singh and others in a disproportionate assets case, hours after the Delhi High Court denied him any relief and removed the interim stay on his interrogation or arrest.
