The management of Indian Life Saving Society (Anderson Club) will show-cause three guards for allegedly failing to alert club officials that Satyabrata

Sen had not shown up after his daily swim in Rabindra Sarobar on Tuesday morning.

The 78-year-old, who was a member of Anderson Club for 23 years, was found dead in the Sarobar, on the banks of which the club is located.

“We have asked the three guards to explain why they would not be suspended,” Amit Bose, senior vice-president of the club, told Metro on Wednesday.

“The guards are supposed to keep watch on the members swimming in the Sarobar. Why didn’t they alert us after Sen failed to show up?”

The post-mortem on Sen’s body was performed at SSKM Hospital on Wednesday.

“Nothing adverse has been found. We have been told that he died because of drowning. The cause of his death would be clear once we get the report,” an officer of Rabindra Sarobar police station said.

“There is no complaint of foul play from the family. Primarily, it appears to be a case of cardiac arrest.”

The resident of Dover Terrace had signed on the register of Anderson Club around 9.40am on Tuesday. He then went to the changing room before hitting the water.

Sen had gone to the club in his son’s car. The driver, who was waiting for him outside the club, alerted Anderson officials when Sen failed to return even by noon.

Club officials launched a search but Sen was nowhere to be found on the Anderson premises. The club then alerted Rabindra Sarobar police station, which activated the Disaster Management Group.

Personnel of the group recovered Sen’s body from the Sarobar around 2.30pm.

Anderson Club has a pool each for children and adults. During winter, when the pools are dry, some members swim in the Sarobar.

Family members have told the police that Sen, who was a civil engineer, had earlier suffered a mild heart attack.

“If a person has a pre-existing cardiac condition, any exertion which is not normal can put pressure on the heart and lead to a sudden cardiac death,” cardiologist Rabin Chakraborty had told Metro on Tuesday.

Some club members said they would often advise Sen against exerting himself too much at his age.

His reply to such entreaties would be: “Ektu swim na korley bhalo lagey na (I don’t feel good if I don’t swim for a few minutes)’.”
