At 3:56 p.m. on Friday, December 6, 1985, a natural gas explosion occurred at the River Restaurant in Derby, Connecticut. It appears that a gas main may have been damaged during the refilling of a sewer excavation. Before anyone became aware of the leak, escaping gas accumulated in the basement of the restaurant and came in contact with an undetermined ignition source. The explosion killed six people in the restaurant, injured 12 other occupants, and completely destroyed the building housing the restaurant. Three people who were not in the restaurant were also injures by the explosion.
