Two men will go on trial today charged with drug offences after a 16-year-old student died of a suspected overdose.

Nicqueel Pitrora, 18, from Croydon, and Ryan Kirk, 21, from Beckenham, both in south London, will go on trial at Isleworth Crown Court in west London.

The pair were accused of being concerned in the supply of class A drugs after Daniel Spargo-Mabbs, 16, died from a suspected drugs overdose following an illegal rave.

It is believed the teenager fell unconscious after taking ecstasy at the party at an industrial site in Hayes, west London, on Saturday, January 18.

Paramedics were called at around 4am and he was taken to hospital and put on life support, but died on January 20.

Following the youngster's death, his father, Tim Spargo-Mabbs, described him as ''a lovely, mercurial kid''.

Speaking from the family home in Croydon, he said: ''This was the first time he'd taken anything and if it could happen to him it could happen to anyone."

His head teacher Richard Parrish described him as ''a boy of huge potential'', who was in the first year of his A-levels and was ''just beginning to find his niche'' .

Pitrora also faces a charge of possession of cannabis and Kirk possession with intent to supply cannabis. Both are in custody.
