Yesterday a 22-year-old mail clerk at the law firm Chadbourne & Parke, located in the G.E. building at 30 Rockefeller Plaza, got his head stuck in the mailroom conveyor belt. Ouch! here's no word yet on just how the unidentified man's head got caught in the machinery, but the Sun reports he’s now in critical condition at Bellevue. OSHA was called in to look at the belt, which was "shut down as a precaution."
