Chandigarh: The Enforcement Directorate on Wednesday conducted searches at several places in Punjab in connection with a drug-related money laundering case involving key accused Jagdish Singh alias Bhola, official sources said.

During these raids the agency has seized about Rs 3.5 crore in cash.

Sources said a total of 13 premises in Rupnagar district were being searched after it was found that "illegal" mining was being carried out on the land which was earlier attached by the ED in the Bhola case.

Sources said some of the accused in this alleged illegal mining case include Naseeb Chand, Shri Ram Stone Crusher and some others.

The drugs money laundering case pertains to a multi-crore synthetic drugs racket that was unearthed in Punjab during 2013-14.

The ED case was registered on the basis of an FIR lodged by the Punjab Police.

The case is commonly known as the Bhola drug case for its identification of alleged "kingpin" wrestler-turned-policeman Jagdish Singh alias Bhola.

Bhola was arrested by the ED in January 2014 and the case is currently pending before the Special Prevention of Money Laundering Act (PMLA) in Punjab.
