VIDEO: Three people—including a 16-year-old girl—were injured in an explosion involving several homes and a ruptured gas line Tuesday in the Southwest Baltimore neighborhood of Pigtown. BGE said in a statement that it completed upgrades in October to the gas main that services the same site as the explosion. Following the explosion, BGE turned off services and stayed onsite to assist Baltimore City first responders. BGE said in a follow-up email to WJZ that the last time one of its employees had been at the site of the explosion was in early November. "There have not been any BGE crews in that area since a technician turned on electric service to one of the homes in the 1100 block on November 3," a spokesperson for BGE said. Chopper 13 flew over the scene on Bayard Street where a home was completely demolished.
