There was trouble at the National Burns Centre (NBC) in Airoli following the death of a patient on Saturday. The patient's angry relatives vandalised the hospital and damaged vehicles parked on its premises.
The family claimed that the hospital had presented an inflated bill reported to be around Rs 7 lakh.
Kalpana Gaikwad (22) had sustained 30 per cent burn injuries following a stove blast on June 1.
She had initially been admitted to KEM hospital at Parel and was shifted to NBC a day later.
Kalpana's family members claimed that she was responding well to the treatment.
Her husband, Dinesh Gaikwad, who works for a shipping company, said: "My wife had been recovering and was shifted to the general ward. She was even walking. Suddenly a few days ago, her condition worsened and she was back in the ICU."
The hospital authorities refuted the allegations of the family, saying the best treatment had been given to the patients and that the fee charged was as per the norms.
The authorities said the condition of some burns patients does worsen even after they seem to have recovered.
Dinesh also alleged: "We were initially told that the hospital bill will be around Rs 3.5 lakh. I will now have to borrow from my friends and relatives to pay the bill."
He claimed that they had even been billed for the visiting charges of a doctor, who was reportedly called from abroad.
Following Kalpana's death at 3 am, a large crowd gathered outside the hospital and started raising slogans against the hospital.
Soon the mob pelted stones damaging the vehicles parked in the area. The glass panes of the security cabin of the hospital too were shattered.
Police vehicles were targeted too.
Kalpana's body was taken for post-mortem to the civic hospital in Vashi after the police and member of Parliament Sanjeev Naik intervened.
Nasser Pathan, senior police inspector of the Rabale police station, said: "We have not received any complaint about the incident but we will register one ourselves after an inquiry in the matter."
