Quick-thinking San Francisco police officers performed CPR on a newborn whose mother gave birth to him early Wednesday on a Bayview District street.

The incident began around 2 a.m. when police received a 911 call from a worker at the Providence Baptist Church homeless shelter at 1601 McKinnon Ave, reporting a woman at their door who was bleeding heavily.

The worker told KTVU he did not see a baby with the woman when he called police.

“She was crying and looked like she was beaten up and covered in blood,” said the worker who did not want his name released. “She said she had just had a baby, but she didn’t have any baby in her hands.”

San Francisco police spokesman Officer Gordon Shyy said arriving officers were flagged down by a man holding a newborn baby. The baby was unresponsive, so the officers requested an ambulance and one officer, a former paramedic, began performing CPR.

The officers then decided to transport the child to the hospital themselves rather than wait for the ambulance.

Meanwhile, the female who was reportedly bleeding had left the area prior to the officers' arrival but was found by police nearby and was determined to be the baby's mother.

Both the mother and baby remain at San Francisco General Hospital and are expected to survive, Shyy said.

The case remains under investigation. Anyone with information is asked to call police Sgt. John Keane of the Police Department's special victims unit at (415) 553-9363.
