A team of officers from the Enforcement Directorate (ED), probing the alleged financial irregularities at RG Kar Medical College and Hospital, conducted a search and seizure operation on Tuesday at the house and nursing home of Sudipta Roy, former chairman of the Rogi Kalyan Samity of the medical college and hospital.

The operation comes within days of a team of CBI officers visiting Roy’s house and nursing home in Sinthee on the northern fringe of the city.

A separate team also visited a bungalow in Hooghly’s Dadpur, believed to belong to Roy, and a medical equipment dealer’s house on Ballygunge Circular Road as a part of the search and seizure operations.

“The man is believed to have supplied medical equipment to RG Kar Medical College and Hospital. The idea is to find out whether RG Kar ex-principal Sandip Ghosh had received any kickbacks from him,” said a senior ED officer.

Besides Roy’s house and nursing home, separate teams from the central agency conducted search and seizure operations at several other locations in connection with the ongoing probe.

Sources in the central agency said Roy’s assets came under scanner after Akhtar Ali, former deputy superintendent of RG Kar Medical College and Hospital, flagged concerns about the alleged irregularities by Ghosh and Roy.

In a letter to the state vigilance commission on July 14, 2003, Ali said Ghosh and a few others were involved in several corrupt practices.

The letter stated: “Misultilisation of Covid fund for creation of gym and furnishing office chamber by procurement revolving executive chair, sofa, dining table, refrigerator etc and I like to inform you that I tried to bring to the notice of the headquarters few months ago ... Sudipta Roy, chairman West Bengal Health Recruitment Board threatened me for termination from job...”

Sources in the CBI said that Ghosh had called Roy on the morning of August 9 to inform him about the death of the 31-year-old postgraduate trainee.

Roy, the Trinamool MLA from Serampore, had reached the hospital that morning after receiving the call from Ghosh. He is also the president of the West Bengal Medical Council, which has show-caused Ghosh over his alleged involvement in financial irregularities at RG Kar.

“We are trying to trace the route that the alleged proceeds of crime travelled as a part of the investigation into alleged irregularities at RG Kar,” the ED officer said.

Calls from Metro to Roy on Tuesday went unanswered.
