Two people have been arrested in London in connection with the suspicious death of a Kilkenny-man who spent a number of years teaching and performing Irish dance in Australia.
The body of Adrian Murphy, 43, was found at a block of flats in Battersea, London on June 4.
A post-mortem examination at St George's Hospital on June 6 failed to determine a cause of death.
Police said property was stolen from the premises where Mr Murphy was found. They also believe he had been using the gay dating app Grindr.
Mr Murphy was a seven time All-Ireland Irish dancing champion and produced and choreographed shows like Celtic Dance Force, Feet of Fire and FireDance The Show.
He performed around the world and, according to his website, set up the Adrian Murphy Academy of Dance across Australia and New Zealand before moving back to Europe, settling in London.
He is the youngest of seven children.
His brother Frank wrote on social media that Murphy died ‘unexpectedly’ at home.
He wrote a poem, saying: ‘I am thinking of you looking at the stars. The colours that you wore of gay with pride. Influenced not by those who disapproved. Your life a whirlwind of the brightest rainbow.’
His death has been linked to an earlier allegation of rape at an address in Walthamstow, north-east London, on May 30.
In that incident, the 40-year-old victim became unconscious after he was allegedly drugged by a man he met on a social networking site and invited to his flat.
He was found later that day by a friend and taken to hospital, but has since been discharged.
His flat had been ransacked while he was unconscious and the Metropolitan Police have said property including laptops, mobile phones and cash were stolen.
A 24-year-old man was arrested on suspicion of murder, rape and theft on June 12.
He has since been bailed to attend a police station at a later date.
A 17-year-old girl was arrested earlier that day on suspicion of murder and theft and has since been released under investigation.
Detective Chief Inspector Rob Pack, from the Metropolitan Police's Homicide and Major Crime Command, said: "We have linked these two incidents through our suspects and our inquiries continue to establish the exact circumstances.
"We know the victim in the Walthamstow incident met the male suspect through a social networking site and we are investigating whether there is a similar connection in Mr Murphy's death.”
