Deputy Commissioner of Police, PCR, Monika Bhardwaj said they received a call around 4.15 am about a woman being injured and crying in pain near a ticket counter at the Old Delhi railway station.
But when the PCR van arrived, the policemen found Preeti was crying in labour pain and her husband, who works as a street vendor in areas near the railway station, was helpless.
The DCP said the police decided to take her to the Lok Nayak Jai Prakash Narayan Hospital Hospital.
She delivered a baby girl in the PCR van with the help of her husband and the policemen.
The woman and the baby were later shifted to the Hospital for further treatment where both are safe, police said.
