A Belfast DJ died after allegedly taking deadly 'speckled Rolex' ecstasy-type pills at a house party in his Twinbrook flat in the west of the city.
It's understood 42-year-old Gerard Mulholland - a well-known producer and DJ on the Northern Ireland club scene - died after taking the pills on Friday night.
Paramedics tried to save the Belfast man but he died at the scene.
Mr Mulholland had been at a house party in his apartment in the Thornhill Court area of Twinbrook on Friday.
It's understood the tragic death happened at around 7.40pm.
Four other people were taken to hospital where their condition was said to be stable.
The death has been linked to yellow ecstasy tablets known as 'speckled Rolex'.
Police appealed for anyone in possession of the pills to dispose of them immediately.
SDLP councillor Brian Heading had said the death of the man was "tragic".
"The tragic loss of life of a man in Twinbrook will be a devastating blow to his family and friends particularly at this time of the year," he said.
"My thoughts and prayers are with them at this very difficult time."
Earlier this year two sudden deaths of people – one in Belfast and one in Coleraine – were linked to another type of ecstasy tablet known as 'green Rolex'.
The pills get their name because of a crown logo stamped on them similar to that of the famous watchmaker and jeweller.
