Kolkata: Trinamool Congress chief Mamata Banerjee, who ended her 25-day fast late last night, is under treatment in the intensive care unit of a hospital here as her heart and pulse rates are low.

Banerjee was under treatment to correct her dehydration, hypoglycaeamia and other nutritional deficiencies, Kakoli Ghoshdastidar, a doctor attending on her, told PTI this morning.

"She is on ogygen unit and intravenous fluid correction," she said.

Investigation was being carried out to ascertain whether any of her vital organs had failed or not, she said.

Anxious party supporters gathered outside the south Kolkata nursing home to know about the health condition of Banerjee.
