Kolkata, Aug 28 (IANS): Probing the multi-crore rupee Saradha scam, the Central Bureau of Investigation (CBI) Thursday raided several places here, including the offices of city businessman Sandhir Agarwal.

Now in CBI custody, Agarwal, accused of extorting crores of rupees from Saradha promoter and scam kingpin Sudipta Sen, was arrested Aug 24.

CBI sleuths also searched the residence of a former East Bengal Football Club official and questioned his widow. Another club official, Debabrata Sarkar, has already been arrested.

Meanwhile, city entrepreneur and the chairman of the now-defunct Xenitis Group, Santanu Ghosh arrived at the CBI officer for his questioning for the second consecutive day.

Ghosh along with Assam-based businessman Rajesh Bajaj were interrogated by the agency Wednesday.

Ghosh, said to have made several business transactions with the tainted group, was arrested in June by the Enforcement Directorate (ED) under the Prevention of Money Laundering Act.

He was granted bail Aug 25 by a city court after the ED failed to submit a charge sheet.

A host of high profile names including West Bengal minister Shyamapada Mukherjee, actress and film maker Aparna Sen, Trinamool Congress MP Ahmed Hassan Imran, and former IPS officer Rajat Majumdar have been grilled by the CBI or the ED in the scam.
