A man who weighs an estimated 600 pounds has been rescued from his home in suburban New York after falling and struggling alone for two days to telephone for help.

Authorities said they used saws to dismantle one wall of David Schock's modular home in Calverton on Long Island to extract him because the 57-year-old was too large to be removed through the front door, Newsday reports.

At least 10 firefighters hoisted Schock onto a custom-built wooden backboard designed for large people, a fire official said.

Schock was taken to a nearby hospital, authorities said. His condition was not immediately available.

Schock was reclusive and his health had deteriorated, neighbors said. They said he had been getting around on a wooden box with wheels.
