Mexico City - A newborn baby was found alive over the weekend in a toilet at a public restroom in a Mexico City Metro station, according to the Federal District Public Safety Secretariat.

The baby girl was found in a restroom at the Constitucion de 1917 station on Sunday morning, the secretariat said.

A cleaning woman told authorities that she heard a baby crying in the restroom and found the child in the toilet with her umbilical cord still attached.

Police officer Isabel Segovia cleaned up the baby and gave her to paramedics, who transported the child to the emergency room at the Pediatric Hospital in Iztapalapa.

The baby was born about 20 minutes before she was found and would have drowned in the toilet bowl if she had not been discovered in time, doctors said.

Investigators are examining video from security cameras at the Metro station and hope to find the woman who abandoned the baby.

The newborn is in good condition, but her mother faces child abandonment charges.
