One Hurt in Detroit Diner Explosion

DETROIT (AP) -- A diner on the city's west side was leveled by an explosion that left one person critically injured, officials said Friday.

The diner, Hanna's Family Restaurant, was closed at the time. A man walking by was injured by debris and taken to Grace Hospital, where he is listed in critical condition, said Detroit Police Sgt. Jesse Cleaver.

Fire Lt. ElDon Parham said the cause of the blast around midnight was unknown, but natural gas played a part. Crews were investigating at the scene.

Firefighters battled the blaze and rerouted traffic after police blocked off the road. The fire was extinguished by 3 a.m.
