Services held for crash victims
Services will be held today to remember those who lost their lives in a horror crash between two cars.
Three 17-year-olds and a 68-year-old woman were killed in the collision which took place in Powys, Mid Wales, as a number of vehicles travelled in a convoy.
The teenagers have been named as Rhodri Miller, Corey Price and Alesha O'Connor, all from Barry, Vale of Glamorgan.
The accident happened on the A470 near Storey Arms, Brecon, between Libanus and RAC bends just before 10.15pm on Friday.
Two vehicles were involved - a black Volkswagen Golf estate and a green Volkswagen Golf. The black Golf is not believed to have been part of the convoy.
It has been reported that Rhodri was driving the green Golf and had only recently passed his test, while Corey was a passenger. Alesha was among three other passengers taken to hospital in a serious condition but she also later died.
The driver and front seat passenger in the Golf estate were taken to hospital, and Margaret Challis, from the Merthyr area, has since died. The driver's condition is described as serious.
Corey was a promising young footballer who trained with the Cardiff City Football Academy.
Dylan Jones, head teacher at Ysgol Bro Morgannwg in Barry, said both boys were very talented in their own way, Corey in football and Rhodri in science.
He told the BBC he had spoken to the families on the phone. He descri "Very devastating. It's been a shock to us all, and a number of their friends also are feeling the shock."
Asked how they would be remembered, he said: "They're remembered as sociable and jolly, and a little mischievous, I'm sure, both of them, but on Monday we will come together to share those thoughts, and be able to reflect on their lives, and hopefully celebrate their lives."
The parents of Rhodri said: "Rhodri was a bright talented 17-year-old who had so much to live for. He was studying for his A-levels at Bro Morgannwg School.
"He was a very popular boy inside and outside of school. He loved his football, was a season ticket holder for Cardiff City Football Club, and loved going to the gym. He will be very sadly missed by family and friends, all who knew him."
Paul and Sharon O'Connor, Alesha's parents, said: "Alesha was a kind loving child, a much loved baby sister and our beautiful princess.
"She was much loved by all her extended family. She was the perfect daughter and friend and has left a massive void in our family. Alesha was beautiful, intelligent and artistic and had her whole life ahead of her. We as a family would like to pass on our sympathy to the other families who have lost loved ones."
The parents of Corey said: "The family of Corey Price are devastated by the sudden and tragic loss of their wonderful gentle and caring son, brother, uncle and grandson. No words can explain how we are feeling but we are truly grateful of the support of our family and friends at this tragic time."
Among tributes paid was a tweet from Cardiff and Vale Schools Football Association, which said: "Hearing terrible news that we've lost a former @CVSFA player in Corey Price. Great player. Thoughts to all his family & friends. #toplad"
Bristol Rovers footballer Mitchell Palmer said: "Very sad to hear about Corey Price, great lad great footballer! Thoughts are with family and friends! RIP big man!"
Dyfed Powys Police said five male drivers, aged 17 and 18, from other vehicles, were arrested on suspicion of dangerous driving.
A spokeswoman said they were released on bail pending further inquiries, as were two other 17-year-old males who were arrested.
The school said on its website there would be services this morning to reflect on what had happened, and an opportunity for pupils to receive further help and support if they need it.
"We will also open a book of remembrance and provide a suitable place to lay flowers in memory of those lost.
"The school would also like to extend an invitation to any former pupils who wish to join us."
Superintendent Chris Curtis said: "This is a tragic incident and our thoughts are with the families at this difficult time.
"We are working with South Wales Police in order to provide support to the families affected and also the communities they live within. We will work with partners to ensure that the incident is fully investigated."
Anyone who witnessed the incident is asked to contact Dyfed Powys Police on 101.
