Investigation continuing after two teenagers die and four others taken to hospital following major incident
Six children were taken to hospital, but two teenage boys, aged 13 and 14, later died. Four other children, aged 11, 10, three, and seven months, remained in hospital last night.
A 37-year-old man and a 34-year-old woman have been arrested on suspicion of murder in connection with the incident.
Friends of the boys have been visiting the scene today with their parents to lay tributes.
One girl, aged 12, described them as “two lovely lads” and told how one of them had raised money for a cancer charity in honour of a friend who had the disease.
She added that they liked football and video games, before breaking down and saying: “They always used to look out for you.
“Everyone is devastated.”
Her mum, aged 45, described the boys as “polite” before adding that her daughter “was crying all night” over the tragedy.
“It is heartbreaking for everyone.”

Jonathan Campbell, aged 50, who lives close to the scene did not know the children but still left flowers.
He said: “It is heartbreaking, really sad. It is bad when anyone dies but especially kids.”
A woman who left flowers at the scene posted on Facebook: “although I don’t know this family my heart goes out to those poor children and the family.
“(I am) praying for the remaining children. What a sad sad day for all involved. My son passed the policeman the flowers and even he had tears in his eyes.”
In addition to the flowers, balloons, one reading ‘thinking of you’, and several teddy bears have also been left.
