Geoff Payne, father of the late One Direction star Liam Payne, has been named in a US defamation lawsuit filed by the singer’s friend, Roger Nores.

The 31-year-old British musician tragically died from “polytrauma”—multiple traumatic injuries—after falling from a third-floor balcony at the Casa Sur Hotel in Buenos Aires in October, according to details revealed at the opening of a UK inquest earlier this month.
