Fans of Liam Payne, the 31-year-old former member of One Direction who unexpectedly died at a hotel in Argentina last week, honored the singer with vigils throughout Europe and Argentina over the weekend. Police said there were between 800 and 1,000 people in London's Hyde Park for a tribute to Payne on Sunday, the BBC reported.

Finally took the step to get my One Direction tattoo, but in the saddest way possible — for Liam Payne," one fan wrote.

London’s Hyde Park was one of the several sites around the world this weekend for an outpouring of love, grief and recollection in honor of Liam Payne, the former One Direction boy band member who tragically fell to his death at a hotel in Buenos Aires last week at the age of 31.
