Two men have been charged with drugs offences after a 16-year-old died from a suspected overdose.
Nicqueel Pitrora, 18, from Croydon, and Ryan Kirk, 20, from Beckenham, both south London, are accused of being concerned in the supply of class A drugs.
They will appear at Uxbridge Magistrates' Court later today.
The pair and another man, 19, who has been bailed until March, were arrested after Daniel Spargo-Mabbs, 16, died from a suspected drugs overdose after going to an illegal rave.
It is believed the teenager fell unconscious after taking ecstasy at the party at an industrial site in Hayes, west London.
Paramedics were called at around 4am on Saturday and he was taken to hospital and put on life support, but died on Monday.
Yesterday his father warned: "It could happen to anyone." Speaking at the family home in Croydon, Tim Spargo-Mabbs described his son as "a lovely, mercurial kid".
The 50-year-old said: "He was up for adventure. He was a really normal kid. He spent a bunch of his spare time with his girlfriend and played a lot on his Xbox.
"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."
Mr Spargo-Mabbs added that Daniel's girlfriend, a fellow pupil at Archbishop Tenison's Church of England High School in Croydon, was "traumatised" by his death.
His mother Fiona said she would always hug and kiss her two sons, Daniel and his brother Jacob, before they left the house.
She told reporters: " Danny always used to say, 'I love you too mum, I promise I won't die'. And that's exactly what he said when he went out on Friday."
His head teacher Richard Parrish described him as "a boy of huge potential", and said the school would pay tribute to him.
Daniel, who was in the first year of his A-levels, was "just beginning to find his niche" and was interested in "a whole range" of things, the teacher said.
