LOS ANGELES (KNX 1070 NEWSRADIO)  -- Police in Modesto say a man tried to cut off his own ARM because he thought he had injected air into a vein while shooting cocaine and feared he would die from an embolism.

33-year-old Michael Lassiter rushed into a Denny's restaurant late Friday night and started stabbing himself in one arm with a butter knife he grabbed from a table.

When that didn't work, he barged into the kitchen, grabbed a butcher knife, and dug it into his arm.

He ended up in a hospital with severe cuts telling officers he thought he needed to amputate his arm to save his life.
