Police in Argentina are still trying to locate Liam Payne‘s Rolex watch after his drug-fueled fatal fall from the third-floor balcony of his hotel room, TMZ has confirmed.

Law enforcement sources tell us … the former “One Direction” singer’s expensive timepiece went missing around the time his body landed in the courtyard of the CasaSur Palermo Hotel in Buenos Aires on October 16.

La Nacion, a Buenos Aires newspaper, reported the watch was not found during police raids on the hotel and the homes of 3 suspects who were arrested last week in connection with Liam’s death.

The defendants — a friend of Liam’s, a hotel housekeeper, and an alleged drug dealer — were charged respectively with abandoning the musician and supplying him with narcotics.

The media outlet says police plan to return to the hotel for another search of Liam’s suite in case they missed the watch during their initial sweep.

La Nacion also claims surveillance footage shows Liam wearing the watch the day he died, quoting a prosecution source who said … “He had it in one of his hands and he had it at least two to three hours before his fatal hotel fall.”
