GREAT BEND, Kan. (KAKE) - Investigators have determined that a gas leak led to an explosion in Great Bend that sent a man to the hospital early Wednesday morning.

The explosion happened shortly after 3 a.m. in the 700 block of East 10th Street. A release from Deputy Fire Chief Brent Smith said it was found the probable cause of the explosion was a significant gas leak inside the residence that was ignited by unnamed source.

"Our testing showed that the gas line from the main to the structure was intact and was not leaking," the release said.

Great Bend police said a man was severely injured in the explosion. Thursday's release didn't provide an update on his condition.

The incident happened at around 3:11 a.m. in the 700 block of East 10th Street. Police say the explosion was heard and felt as far away as Ellinwood, which is about nine miles from the scene.

Police Chief Steve Haulmark said a man was severely injured in the explosion. The home was destroyed. There was also "significant" damage to neighboring buildings and cars.
