An ambulance carrying a heart attack victim to Kolkata on Wednesday was kept waiting near an expressway as policemen waited for Chief Minister Mamata Banerjee's convoy to pass, The Times of India reported. 

This even after the patient's doctor pleaded with folded hands to the cops to let them go, the report states. One of the cops even allegedly checked the woman's pulse and concluded that she could wait till the convoy passed. 

Banerjee was supposed to return from Digha to Kolkata and police weren't certain whether the CM would arrive via road or air. She took a helicopter to the city eventually. 

The patient, 50-year-old Meherjan Begum, had to wait for around 20 minutes on her way to the SSKM Hospital in Kolkata as the ambulance was stuck in the traffic stopped by cops. 

The ambulance was allowed to go after senior police officials came to know of her condition and intervened. 

According to the TOI report, Meherjan's relative Md Aziz said that she has been admitted in the cardiology department of the hospital and is in a critical condition. A doctor said that while she has a complete heart blockage, her condition is stable now.
