New Delhi, Jul 2 (IANS): Leader of the Congress in the lok Sabha, Adhir Ranjan Chowdhury has slammed the Enforcement Directorate (ED) for grilling party treasurer Ahmed Patel, who has been interrogated for the third time on Thursday for links with promoters of Sterling Biotech.

Congress leader levelled allegation that Sterling Biotech promoters have links with Rakesh Asthana, an IPS officer.

Chowdhury alleged, "Modi ji's most trusted man Mr Rakesh Asthana, IPS, has been implicated as a recipient of bribe money which has been exposed in Sandersara diary. I am flagging the attention of Narendra Modi Ji, but Congress party's leader Ahmed Patel Ji has been grilled for 3 consecutive days by ED to unearth the nexus between Patel Ji and notorious Sandesara case."

A team of Enforcement Directorate (ED) again on Thursday arrived at Patel's residence for the third time in less than a week to question him in connection with its probe into multi-crore bank fraud case by the Gujarat-based Sterling Biotech.

The ED had earlier questioned Patel on June 27 and June 30 for several hours under the Prevention of Money Laundering Act (PMLA), 2002.

A team of financial probe agency officials arrived at the 23, Mother Teresa Crescent Road here on Thursday morning to record Patel's statement once again.
