One Direction star Liam Payne died of multiple traumatic injuries, a UK inquest into his death has heard.

The 31-year-old singer, who died in October after falling from the third-floor balcony of a hotel in Buenos Aires, Argentina, was confirmed to have died of "polytrauma", the inquest opening heard.

The hearing, which Buckinghamshire Coroner's Court said was held on 17 December, was told it may take "some time" to establish how Payne died.

The inquest into Payne's death in the UK has been adjourned until a pre-inquest review on 6 November, the coroner's court said.

Five people have been charged over Payne's death at the Casa Sur Hotel on 16 October.

The hotel's manager, a receptionist and a "representative" of Payne have been charged with negligent homicide (similar to manslaughter in UK law), Argentina's National Criminal and Correctional Prosecutor's Office previously said in a statement.

They are hotel manager Gilda Martin, receptionist Esteban Grassi and Payne's "representative" Roger Nores.

Two others, hotel employee Ezequiel Pereyra and waiter Braian Paiz, have been charged with supplying cocaine.

Family and friends attended Payne's funeral on 20 November, including his girlfriend Kate Cassidy and former partner Cheryl, with whom he had a son, Bear.

His One Direction bandmates, Harry Styles, Louis Tomlinson, Niall Horan and Zayn Malik also attended the private ceremony.

Senior Coroner Crispin Butler said during the inquest hearing: "Whilst there are ongoing investigations in Argentina into the circumstances of Liam's death, over which I have no legal jurisdiction, it is anticipated that procuring the relevant information to address particularly how Liam came by his death may take some time through the formal channel of the Foreign, Commonwealth and Development Office."

It comes after the star's final hours were recently detailed by a judge and the Argentinian Public Prosecutor's Office, who said in a statement Payne had been "demanding" drugs and alcohol during his stay at the hotel.

On 16 October, Payne was in the hotel lobby and "unable to stand" due to the "consumption of various substances", the court document said.

The receptionist and two others "dragged" the singer to his room.

The document also reiterated the hypothesis that Payne had "tried to leave the room through the balcony and thus fell".
