The Detroit News Published 11:55 AM EDT Sep 21, 2018 Harper Woods — A house exploded Friday morning in a densely populated residential area of the city near the border of Grosse Pointe Woods. The house was located in the 20800 block of Lennon Street, near the Interstate-94 Service Drive, just south of Vernier. “The house, as you can see behind me, has completely been knocked down,” Harper Woods Police Chief Jim Burke said. “We believe it’s a gas explosion at this time.” Two people are hospitalized in critical condition, Burke said. Burke said it is expected their conditions will improve. A DTE Energy Co. spokesman said they are investigating the incident but it was too soon to confirm whether the explosion was caused by a natural gas leak. Police have asked the public to avoid the area from Beaufait to Van Antwerp and Harper to Canton.
