Tributes have been paid to two teenage men who died after apparently taking drugs at a nightclub in Plymouth.
The family of Aaron Reilly, 19, from Newton Abbot, described him as a "a much-loved son, brother, grandson and boyfriend".
In a statement, his younger brother Kian said: "My brother was one of the most responsible people I ever knew and everything he achieved I was so proud of, but I was so envious of his talent.
"I can't believe he was taken from me and my family from one silly mistake, just trying to have fun on a night out with his best mates."
He was found unconscious at 1.40am Saturday morning (9 December) at the Pryzm nightclub in the Devon city along with Joshua Brock, also 19. The men died later in hospital.
Brock, from Okehampton, was in his third year studying for a diploma in aircraft engineering at the Flybe Training Academy in Exeter.
His family said in a statement: "He was the kindest, most helpful person you could hope to meet and had a great sense of humour.
"His main hobby was keeping fit and eating healthily, so what happened that night is so totally out of character as he was always against drug taking in any shape or form. One moment of madness led to this tragedy."
An 18-year-old man who was arrested in connection to this incident has been released under investigation, pending further enquiries, Devon and Cornwall police said.
Detective Inspector Julie Scoles, said: "It is currently believed that the two men who died were part of a larger group who had taken what they thought to have been MDMA."
