A man has been arrested after a 40-year-old woman who was shot dead in Talbot Green, about 15 miles west of Cardiff.
The woman was found with serious injuries in the Green Park area of the Welsh town just after 6pm on Sunday and could not be saved by emergency services, south Wales police said.
A 42-year-old man from Talbot Green was taken into custody, police said. Several crime scenes were set up in the area by investigating police and roads were closed.
Det Ch Insp James Morris said: “I understand the concern this will cause the local community, and I want to reassure people that a team of experienced detectives are already working at pace to piece together the events of last night.”
Rhondda Cynon Taf (RCT) county borough councillor Sarah Jane Davies called online for residents to “stay vigilant” and thanked them for cooperating.
