A Quebec man who lost his lower leg after an air compressor exploded in Chelsea, Que., has died, MRC des Collines police confirmed Monday.

The 44-year-old man and two friends were working to restore an antique car on Saturday at a home on Chemin Maxwell when the explosion happened at about 12:30 p.m. ET.

When officers arrived, they said they found three men injured.

The 44-year-old man had suffered extensive damage to his lower leg, forcing doctors to amputate the leg at the knee in hospital. Police said on Monday he later died.

Another man, who is 50, suffered head and back injuries, while a 58-year-old man was treated as a precaution but did not suffer any major injuries.

Police believe the compressor was old and had been damaged by rust, partially causing the explosion.
