A man being treated at a Long Island hospital started a fire inside the emergency room early Friday morning, Nassau County police said.
Patrick Callahan, 26, of Levittown, "became agitated and uncooperative" and took a lighter from his pocket and ignited the bed sheets, mattress, and gurney he was in, police said.
The emergency room, which is littered with oxygen tanks, filled with smoke while hospital staff retrained Callahan and extinguished the flames, police said.
Two other patients were in the room with Callahan, and the ER had 52 other patients, family members, and staff, police said.
Authorities charged Callahan with reckless endangerment, criminal mischief, and arson. Police also discovered that he had an open warrant for disorderly conduct.
Callahan was arraigned later Friday at First District Court in Hempstead, police said.
