The father of a County Antrim man found dead in Ibiza says he wants answers after allegations were made that his son was beaten by Spanish police.

Friends of Alan Drennan have claimed the 21-year-old sustained head injuries when he was beaten by officers after arriving on the island on Saturday.

He was found dead in his hotel room on Sunday, less than 24 hours later.

A solicitor for the family is speaking with Spanish, British and Irish authorities to establish how he died.

Mr Drennan Jr was a mechanic and doorman from Newtownabbey.

The PSNI has said it is assisting Spanish police in the investigation into the death.
