Police are investigating what they described as the "sudden and unexplained" death of a three-year-old boy in Cardiff.
South Wales Police said officers were called to a house in the Cathays area of the city at 5.40pm on Monday, June 29.
A spokesman said the "cause of death has not been confirmed".
An investigation has been launched by police and is ongoing. There have been no arrests.
The Home Office is also involved in the case. It said it was working with its accommodation providers and other authorities to support them in the investigation.
In a statement, the Home Office said: "We are aware of an incident in which a young child sadly died.
"Our thoughts are with their family and we are working with the local authorities and our providers to ensure they have as much support as possible.
"It would be inappropriate to comment while an investigation is ongoing and before all of the facts have been established."
