Man held after two people are killed in shocking city centre incident
A man has been arrested on suspicion of murdering two people in a city centre.
South Wales Police detained the 20-year-old, from the Castleton area of Gwent, following the discovery of the two bodies in Queen Street, Cardiff, at 5.50am on Wednesday.
He was arrested with the assistance of Gwent Police officers at an address in Castleton within an hour of the incident being reported.
A force spokesman said the man was being held at Cardiff Bay police station and officers are not looking for anyone else in connection with the deaths.
The identities of the two victims - a 33-year-old man and a 21-year-old woman, who both lived in Cardiff - have been established and their families have been informed.
Post-mortem examinations will take place to determine the causes of their deaths. At this stage it is believed that both victims suffered stab wounds.
Chief Superintendent Belinda Davies, of South Wales Police, said: "This incident occurred in the main shopping area in the heart of the city in rush-hour and it has no doubt shocked the community of Cardiff.
"Please be reassured that we have a team of officers investigating what happened and importantly we have a suspect in custody and we are not looking for anybody else.
"We are in the very early stages of the investigation but I would like to add that at this stage we believe the suspect was known to the victims and it was not a random assault.
"I would like to dispel speculation circulating as to the motive behind this tragic incident and make it clear that this is not being linked to terrorism, and any links to the homeless community are unfounded."
A large section of Queen Street, the Welsh capital's main shopping thoroughfare, has been cordoned off.
Members of the public are unable to access much of the pedestrianised area, which is now being treated as a crime scene.
Stores including Topshop, Zara, River Island, Boots and Primark, did not open on Wednesday morning.
"The ongoing understanding and co-operation from the public and business community is very helpful," Ms Davies said.
"I would also like to appeal for people to be mindful that this is a very traumatic time for families involved in the incident and to use their better judgment when sharing and using images on social media.
"Our thoughts are with the families involved at this tragic time."
