Hollywood actor Jeremy Renner's nephew recounts the 'Avengers' star's horrific snow plough 

accident in new body camera footage released by the Washoe County Sheriff's Department.

On January 1, Renner was run over by his Sno-Cat, a large snow plough that weighs at least 14,330 pounds

, as he attempted to help his 27-year-old nephew, Alex Fries, free a pickup truck lodged in the snow.

When Renner exited his Sno-Cat to check on Fries, the vehicle kept moving. 

The actor was stuck under the plough's tread as he tried to stop it from hitting Fries.

In the footage, obtained by news, Fries is heard telling law enforcement, "He got out to tell me something, and then that's when it started coming at me, full force."

"Right where his blood is at, that's where it all happened," Fries told officers, adding, "He tried to jump on it, into the (snow plow), and it took him under."

Renner was hospitalised for blunt chest trauma and orthopedic injuries after the accident, later revealing that he broke over 30 bones.

Since the incident, the actor updated fans with his progress on social media, posting a video of himself in physical therapy in February with the caption, "Whatever it takes," a nod to "Avengers: Endgame."
