Sandip Ghosh, the arrested former principal of RG Kar Medical College and Hospital, where the 31-year-old postgraduate trainee was raped and murdered on August 9, owns two other apartments in Beleghata apart from a house on Badan Roy Lane in Phoolbagan, the CBI said.

One is a ground-floor apartment on CIT Road in Beleghata and measures around 1,200 sq ft and the other, on the second floor, is spread over 1,400 sq ft, CBI sources said.

An SUV, bought in June 2022, remains parked in the garage. A few badges bearing the names of RG Kar Medical College and Hospital and that of Calcutta National Medical College and Hospital are on the SUV’s dashboard, the sources said.

Unlike Ghosh’s other properties that the ED went to on Friday, including a villa in Canning, South 24-Parganas, the apartments on CIT Road do not bear his name, the sources said.

The building is located close to Ghosh’s multi-storeyed house in Phoolbagan. The CBI has yet to find out why the apartments do not bear his name. “It is important to find out when Ghosh bought these two apartments and the garage at the CIT Road address. The source of funds may have a link with the alleged financial irregularities,” said a CBI officer.

The building’s caretaker, Binod Das, told reporters that Ghosh visited the apartments occasionally. The one on the ground floor was meant to be an office.

“I don’t know what the office was for. Sir (Sandip Ghosh) bought the car a few years back and it now lies in the garage,” Das told reporters.

On September 2, the CBI arrested Ghosh along with three alleged accomplices — Afsar Ali, Suman Hazra and Biplab Singha — for their alleged involvement in the financial irregularities at the medical college.

CBI sources said the agency was probing the criminality and the ED the alleged parking of proceeds of crime and the money trail.

Ghosh’s wife told reporters when an ED team turned up at their Phoolbagan home for a search and seizure operation on Friday that her husband had not committed any crime.

“He is not involved in any financial irregularity. We have been cooperating with all the investigating agencies and will continue to do so. No documents have been seized so far,” the woman, her face covered with a scarf and shades, had told reporters.

The CBI has said that Ghosh and the other three were part of a “great nexus”.

The CBI’s lawyer, Ram Babu Kanojia, told the special CBI court on Tuesday that the nexus was involved in granting favours for money at RG Kar.

The CBI is also probing the role of Afsar Ali, an additional security guard posted with the erstwhile principal, in selling biomedical waste like syringes, gloves and used saline bottles.

Apart from the properties linked to Ghosh, separate ED teams had visited several addresses across the city and its adjoining districts on Friday. They included Kunal Roy’s house in Baidyabati, Hooghly, and businessman Swapan Saha’s house in Salt Lake.

On Saturday, sources in ED said they were trying to find out if the two were part of a company that was involved in selling biomedical waste, a part of which was collected from RG Kar.
