A seven-year-old boy who was found dead outside a home in Birmingham has been named as Hakeem Hussain.
The boy was discovered by paramedics at around 7.30am on Sunday at a property in Nechells.
Speculation arose that Hakeem, also known as Hakeem Mahmud, had frozen to death, but officers said a post-mortem examination of his body was inconclusive.
Further tests will be carried out.
A man and a woman were arrested on suspicion of wilfully ill-treating a child, but were released under investigation.
DI Jim Munro said: “This is a tragic case and has understandably had a huge impact on the community.
“We are keen to hear from anyone who knew Hakeem as we continue to build up a picture of the circumstances surrounding his death.”
Paying tribute to Hakeem on behalf of children and staff at Nechells E-ACT Academy, where he was in year three, headteacher Julie Wright said: “Hakeem was a most beautiful little boy, a great friend to many staff and children with a wicked sense of humour and an infectious giggle.
“He was a warm and generous-hearted soul who was talented across many areas of the curriculum but especially so in music and the arts.
“His performance as the ‘Christmas Star’ in the year two nativity play last year will stay with me forever as he totally stole the show with his clear speaking voice and stage presence.
“There wasn’t a dry eye in the house as he delivered his lines with poignancy, grace and humour.
“The twinkle in his beautiful eyes was as bright as the stars in the sky, and our love for him will shine out forever, from all of his Nechells family. Hakeem will be sorely missed by us all.”
