An off-duty paramedic and police had to create makeshift tourniquets to stop the bleeding after a man sawed his arms in a Home Depot.
Police were dispatched to the West Covina store about 12:20 p.m. Wednesday after customers saw the man grab a handsaw and begin cutting into his arm, police said.
"He just began sawing away," West Covina police Cpl. Rudy Lopez told The Times, saying the man had calmly grabbed the handsaws.
"He was pretty much intent on doing what he did," Lopez said. "Nobody noticed him until he started doing what he was doing."
