Horrified shoppers could only watch as a "crazed" man tried to cut off his arms by sawing them both to the bone in a busy suburban Home Depot store in West Covina, Los Angeles.

Customers at the home improvement outlet watched as he grabbed several small saws - usually used to cut sheet rock - and began slicing open his arms.

He soon passed out on the floor in a pool of his own blood.

An off-duty paramedic was shopping nearby and sprang into action - collecting twine and rags from shelves to secure makeshift tourniquets over the wounds.

It was a move that probably saved the man's life, West Covina police Cpl. Rudy Lopez told KTLA.

The man, who has not been identified, was taken for surgery at Queen of the Valley Medical Center.

His current condition is not known and it's unkown why he carried out Wednesday afternoon's brutal attack on himself.

The store remained shut for the rest of the day.
