(CNN) -- The mother of a newborn rescued over the weekend from a toilet pipe in China "deeply regrets what she did," police said Tuesday.
The infant, a baby boy, was saved Saturday in the Chinese city of Jinhua. He remains in the hospital, where he is reported to be in stable condition.
"Local police have found the mother. She deeply regrets what she did. Details of the case are still under investigation," Jinhua police said on the social media website Weibo.
They posted images of the baby, showing him sleeping in an incubator and being attended to by various nurses.
Dramatic video of the infant's rescue made global headlines and sparked sympathy.
According to police, one of the firefighters involved visited the baby and sent over clothes, formula powder and diapers.
Someone else sent milk bottles and formula, along with a note that read: "Don't let the baby starve. Let's pray," they said.
The rescue began after cries were heard from a fourth-floor apartment toilet.
Alarmed neighbors heard the sounds and saw a tiny foot inside a ceramic bowl.
They called the fire department, state broadcaster CCTV reported.
Unable to pull the infant out out, rescuers went to the floor below and sawed away a section of pipe.
But still, the baby was stuck, so both the section of pipe and the infant were taken to a hospital.
Working together, rescuers and doctors began removing the pipe, piece by piece.
CCTV video showed the exact moment hands in white gloves gingerly pulled away a part of the pipe, revealing the tiny face of a newborn.
