New Delhi: The Enforcement Directorate (ED) has attached property worth Rs 14.48 crore of former government engineer Yadav Singh as part of its probe in a corruption case against him, an official said on Wednesday.

"We attached assets worth Rs 14.48 crore of Yadav Singh in a disproportionate assets case worth Rs 23.15 crore. The attachment made under Prevention of Money Laundering Act. Total attachments worth Rs 20.38 crore have been made in this case till date," the ED official said.

The attached properties belong to Singh, his wife Kusum Lata and their two companies - Kusum Lata Garments Pvt Ltd and K.S. Ultratech Pvt Ltd.

The ED seized Singh's three properties in Gautam Budh Nagar worth Rs 1.28 crore, cash in banks amounting to Rs 29.46 lakh and movable assets in Noida Sector 51 worth Rs 44.97 lakh. The agency also confiscated 18 properties of Singh's wife situated in Agra, Mathura, Gautam Budh Nagar and Delhi amounting Rs 7.32 crore.

The ED also seized properties worth Rs 4.65 crore and Rs 46.75 lakh belonging to Kusum Lata Garments and K.S. Ultratech respectively.

Singh was engineer-in-chief of the Noida Authority, Greater Noida Authority and Yamuna Expressway Industrial Development Authority in Uttar Pradesh.

Raids conducted by the Income Tax Department in November 2014 revealed that Singh owned huge property disproportionate to his known sources of income.

He was suspended by the Uttar Pradesh government in February 2015 and one-member judicial commission to probe into the multi-crore case set up by the state government. He was arrested in February 2016.

The Central Bureau of Investigation (CBI) has registered three FIRs against Singh, with the most recent one filed on January 17, for allegedly misusing his official position for awarding contracts in violation of norms.

The two previous cases were lodged against Singh and others in July 2015 after the Allahabad High Court directed the CBI to probe the case stating that the allegations were most serious and the probe was complex.

The ED is probing money laundering charges against Singh who has been chargesheeted in two cases. The CBI had filed charge sheet against Singh and others for disproportionate assets worth Rs 23.15 crores.

Singh is presently lodged in judicial custody at Dasna jail in Ghaziabad.

Singh's son Sunny and daughters Garima and Karuna are also accused in the CBI FIR. Singh's family is alleged of utilising his illegal money to form a company.
