A second post mortem will be carried out in Dublin today by the State Pathologist, on the body of a Co Antrim man who died in Ibiza 10 days ago.
It follows complaints made to the PSNI by seven friends of 21-year-old Alan Drennan, that he was beaten by Spanish Police after he was escorted from a plane after his arrival. Many of them have posted messages to a facebook memorial page.
Mr Drennan, from Newtownabbey, near Belfast, went out with his friends after the incident but was found dead in his hotel room the next day.
An earlier Spanish post-mortem examination concluded he had died from multiple organ failure.
The second post mortem cannot be undertaken by the Northern Ireland Coroners Service because it does not have the authority to investigate deaths that happened outside its jurisdiction.
Mr Drennan's family are appealing for anyone with information to come forward.
Their solicitor Michael Madden appealed to anyone who was in the airport or the San Antonio area of Ibiza on Saturday and Sunday July 18/19 to check their photos and videos for footage of Mr Drennan.
“There might be photos there, there might be videos there and there may be signs and images of Alan there that they don’t even realise that they have which could be helpful to the investigation and any possible inquest,” he said.
