Pc Dan Wells was driving in Fulham Road when a BMW raced past him and pulled over. The driver, Russian banker Michael Nadel, 39, flagged down the police car and told the officer and his partner that his wife Natalia, 31, was about to give birth. Pc Wells said: "The head was out and we could see the umbilical cord wrapped around the baby's neck. I told the mum to push and out came the baby. I took the umbilical cord from her neck and handed her to mum."
