Harry Potter actor Dave Legeno has died while hiking in California, police in the US have confirmed.
British actor Legeno, 50, who played werewolf Fenrir Greyback in three Harry Potter films, was found in a remote part of Death Valley by a pair of hikers in the early hours of Sunday, the Inyo County Sheriff said.
It is believed Legeno, who was also a mixed martial arts fighter, died of heat-related issues, police said.
A sheriff's department spokesman said there were no signs of foul play.
Fellow Harry Potter star Tom Felton, who played Draco Malfoy, paid tribute to Legeno on Twitter.
Legeno, who also starred with Brad Pitt in Snatch and in the 2005 remake of Batman Begins, was set to be in upcoming film Sword of Vengeance.
