A heartbroken mother has spoken of her son who died after taking ecstasy at an illegal rave, revealing the last thing he promised before going out was that 'he wouldn't die'.
Daniel Spargo-Mabbs, 16, died in hospital after an apparent overdose after taking the drug on the weekend.
Two men aged 18 and 19 have been arrested for supplying controlled drugs.
His mother, Fiona, told the MailOnline that Daniel's last words before going out on Friday night were: "‘I love you mum, I promise I won't die."
Mrs Spargo-Mabbs said: "This is all just so unreal. I feel I must come across as really inhuman because I'm not in floods of tears. My boys are the loveliest boys in the whole world.
"I know every mum says that but mine really are. And I just don't know how I am going to go on. I don't know what you are supposed to do. This is all so incredibly unreal.
"Every now and then reality hits me and it's just awful. At the moment I quite like the unreality because the reality is just too much. Daniel had never taken drugs before."
Daniel's father, Tim, said Daniel was "a lovely mercurial kid".
"This was the first time he'd taken anything and if it could happen to him it could happen to anyone. We very much want to get that message across," he told the MailOnline.
Archbishop Tenison’s Church of England High School principal Richard Parrish said students were informed of the death yesterday.
"Sometimes you hope that the worst thing won’t happen. Sometimes it does happen anyway. And yesterday it did," he said.
