A 51-year-old woman collapsed to death during her routine morning walk on a footpath along Southern Avenue on Monday.

She was declared dead at SSKM Hospital, police said.

Subhra Ghosh, 51, a resident of Jatin Das Road, had been visiting Southern Avenue and Rabindra Sarobar regularly for her morning walks.

On Monday, around 8.40am, she was walking alone near Lake Kalibari when people saw her collapse on the footpath.

Morning walkers alerted the local police station. The police took her to SSKM Hospital in an ambulance.

“We also alerted her family members through her mobile phone. They reached the hospital with their family physician. We learned from the family members that she had undergone a heart surgery recently,” said an officer at Rabindra Sarobar police station.

She was examined by her family physician and declared dead at SSKM Hospital.

“The family physician gave the death certificate stating the woman had a heart ailment and that she died because of a cardiac failure,” said the officer.

The body has been handed over to the family.

Hundreds of men and women, especially elderly persons, visit Rabindra Sarobar and other lake areas across the city for their morning and evening walks.

Senior officers at Lalbazar said that it was always advisable for them to carry some kind of identity cards so their families could be contacted during an emergency.

“It is best not to allow the elderly to step out of home alone. If they do, they should carry identity cards mentioning all contact details,” said a police officer in Lalbazar.
