A young mother has been charged after allegedly leaving her eight-month-old son in a Bristol railway station toilet, British Transport Police said.
The baby was found uninjured in a ladies toilet at Bristol Temple Meads on 14 November.
The 25-year-old woman, who is from South Wales but was living in Devon, was charged with exposing a child to danger and was bailed.
A spokesman for British Transport Police said: "The mother of the child is 25 and was living in Devon.
"She was arrested in Torquay and has been charged with exposing a child to danger (Section 27 of the Offences against the Person Act 1861)."
The woman is due to appear in South Devon Magistrates' Court on 4 December.
The baby is being looked after by Rhondda Cynon Taf Council's social services, according to local reports.
A council spokeswoman told Wales Online: "We understand the police are currently investigating an incident where a baby was found at Bristol Temple Meads.
"The baby was taken into the care of Rhondda Cynon Taf Council and we can reassure your readers the baby is safe and being well cared for.
"Any further comment would be inappropriate at this time."
