Police were called to the canal, just off Treaty Street near King’s Cross, on Saturday (May 3) at 12.57pm to reports of a woman and baby in the water.
Members of the public took them both out, and when police arrived both the baby and woman became unwell after having an “unknown substance”.
They were taken to hospital and their conditions are still being assessed, although it’s thought to be non-life threatening.
A cordon remains in place near Treaty Street and Copenhagen Road.
The 27-year-old woman has now been arrested on suspicion of attempted murder.
