Wayne Rooney, who was celebrating becoming PFA Player of the Year, is escorted from the nightclub early today
The teenager from Lisbon, Portugal, collapsed in the club at approximately 1.20am.
He was then taken to a central London hospital where he later died.
Another man was arrested on suspicion of supplying class A drugs.
A team of paramedics battled to save the clubber's life as he lay on the pavement outside the nightclub. This morning the club was still cordoned off as police carried out further inquiries.
Rooney had been at the club along with his brother Graeme and fellow England footballer Ashley Cole after he was earlier awarded the PFA Player of the Year Award.
The player looked baffled by the commotion outside the club as he left but his spokesman claimed the footballer was 'unaware of any incident having taken place'.
The spokesman added: 'As Wayne was leaving the club he was asked - as were all other guests - whether he had seen anything.
'He simply told police that he had seen nothing and was not aware of any incident.'
