A mother has paid tribute to her four-year-old son after he was taken ill at home and died later in hospital.

The child, named locally as Louie Eastall, was rushed to hospital in south London after mother Hollie could not wake him at their home in Surbiton.

His death is being treated as unexplained and the Metropolitan Police have launched an investigation with officers from the sexual offences, exploitation and child abuse command conducting inquiries.

It is understood the child abuse team investigates as a matter of routine in any unexplained deaths of children.

Single mother-of-three Miss Eastall posted pictures of her son on Instagram and Facebook and revealed her heartbreak.

She wrote: ' My heart is broken. My beautiful boy gained his angel wings during the early hours of this morning.

'I woke up to find he had left, he chose to do it while mummy was sleeping as he knew I wouldn't be able to live with myself if I saw.

'RIP to my beautiful my amazing boy. 'I will never forget you, I love you with every ounce of my soul (sic).

'You were just too pure for this world.'

She later posted: 'I will never let memory fade. God gave you to me because he knew I would love out more than the world itself.

'Thank you for letting me be your mummy and for spending four beautiful months with you.

'You didn't leave me when you was so poorly you knew it wasn't time, not yet.

She added she 'did not understand why he had gone' and that he was 'in heaven now'. The child's death is being investigated and is being treated as unexplained

'I don't understand why you have gone and it hasn't fully sunk in baby but it will soon.

'That's when my heart will ache. I love you Louie Eastall and I always will.

'Now go and fly and play with all the other angel babies up in heaven for you are just too pure and innocent for this cruel world.'

Friend Rio Wicks has since set up a GoFundMe page for Louie's burial raising over £1,975 of its £2,500 goal raised by 108 people in 20 hours.

She said: 'On the 10.04.2017 Little louie was taken too early at just 4 months old and sadly although hollie cant get him back she just wants to make sure she can give him the best send off ever.

'As funerals costs a huge amount and Hollie is a single mother to two other small children if everyone could please donate even the smallest amount it would help towards the cost of the funeral and she would be so grateful.'

Writing on the post Sandra Smith who donated £10 said: 'My heart breaks for all of you, god bless Louie, you are amazing Hollie, xxx'
