The deaths of two people found in a house in a valley community are being treated as “unexplained,” police said.
Inquiries are under way after the discovery of what is believed to be a woman and a child in a south Wales village.
Residents in the close-knit community of Troedyrhiw, near Merthyr Tydfil, are in shock this morning, South Wales Police said.
The bodies, neither of which have been formally identified, were found in a house in Church Street at 4.20pm yesterday.
Police forensic teams are on the scene and trained family liaison officers are supporting the next of kin. Post-mortem examinations have been arranged.
"Officers are continuing to carry out house-to-house enquiries in the area. A police cordon remains in place in Church Street," a police spokesman said.
"The deaths are currently being treated as unexplained and an incident room has been set up at Cardiff Central Police Station."
Detective Superintendent Paul Hurley, of the South Wales Police Specialist Crime Investigations Team, added: "Troedyrhiw is a close-knit community in Merthyr Tydfil and local people are obviously shocked.
"We have a team of officers at the scene and in the community looking for information that may assist our enquiries.
"We would like to hear from anyone who has seen or heard anything suspicious or unusual in Church Street in recent weeks. The information may seem insignificant but could be important to the investigation."
Borough councillor Gareth Lewis said he found out about the incident on Twitter and added that it would be wrong to speculate on the nature of what had happened.
He said: "All we know is that a child and somebody else, perhaps a young adult, have lost their lives.
"It is a very close-knit community, the people are very nice and will help the police as much as possible with their inquiry.
"The information started to spread online, and it will have a big impact on this community and its people."
Troedyrhiw is part of an old coal mining area, which Mr Lewis described as a "typical, traditional Valleys community".
