Ibiza death: Alan Drennan's friends claim he emerged from Spanish police custody with 'clearly visible injuries'
Friends of Alan Drennan - the young Northern Irish man found dead while on holiday in Ibiza - claim he had "clearly visible" injuries to his head and upper body when he was released from police custody.
A statement has been released by solicitors representing Mr Drennan's family, who are awaiting post-mortem and toxicology reports in their quest to establish how he died.
Friends allege he was beaten by Spanish police.
Michael Madden of Madden & Finucane solicitors is in protracted discussions with Spanish, British and Irish authorities and consular officials.
"The full post-mortem report has not yet been completed and the exact cause of death is unlikely to be established for a number of months due to the timescale for the availability of the toxicology report," the statement said.
"At present the family have more questions than answers.
"Alan's friends have raised a serious allegation that he was assaulted by Spanish police officers prior to his death causing injuries to his head and upper body which were clearly visible to his friends upon his release from police detention at the airport. We are assisting the family in trying to establish the truth of all possible contributory factors which led to Alan's death."
PSNI detectives are assisting the Spanish investigation by speaking to any potential witnesses in Northern Ireland.
Mr Drennan's father, Alan Drennan Senior, said: "What has happened to Alan and our family is every parent's worst nightmare and we want to find answers not just for us but for everyone else's child who goes abroad on holiday and particularly to Ibiza."
