Tributes have been left at the spot where a "lovely" mother and her young son were fatally injured in a head-on collision on Saturday.

Nikki Morris, 29, and Kai Arnold, 11, died after a Ford Focus and Ford Fiesta crashed on a bend in Banstead Road, Ewell, on Saturday at about 10.30am.

A stream of parents and Kai’s schoolmates, from Woodmansterne Primary School, Banstead, left flowers, teddy bears and notes by the roadside today.

A friend, who visited the scene, said she had heard Kai died in the arms of his father Dave who was also involved in the crash.

She said: "The fact he has lost them both is just awful. It’s just terrible. I can’t believe they are gone. Two lovely people. It’s hard to put into words how it feels."

The woman went to school with Ms Morris as a girl and her daughter went to pre-school with Kai and had been due to start at the Beacon School with him in September.

She said: "You couldn’t ask for a better mum. She would help anyone out. Kai was a little sweetheart. The good go young."

She added: "We had a saying at school, live life to the full. She did that, she went out and enjoyed herself."

She said they had seen the family again at an induction at the Beacon School on Wednesday night and she found photos of Kai at a birthday party while clearing out the loft on Saturday.

She said: "A couple hours later, we read on Facebook that they had gone. My daughter didn’t want to go to school. She wanted to come here herself. She’s in shock."

She said that Ms Morris had been engaged to Mr Arnold and Kai’s younger brother Alfie had not been in the car because he was at a sleepover.

She said: "He came close to losing his dad as well."

Linda Lewis, who has lived in Banstead Road for 18 years, said three air ambulances and about 10 ambulances were called to the scene of the crash.

Mrs Lewis said: "The paramedics are the heroes of the whole day. The emergency response was fantastic. A family is devastated in a blink of an eye. It is very sad."

Although there is no suggestion that this accident as caused by speeding, Mrs Lewis said the road is dangerous and more needs to be done to stop boy racers and other drivers from speeding down the road at up to 70 miles per hour.

She said: "That speeding with the double bend is just lethal and two people have died. Since I have lived here there have been about five serious crashes where the road has been closed."

Mrs Baggaley said: "I could have been involved. I was only three cars away. It’s very, very tragic. But will they ever get to the bottom of whose fault it was?"
