The circumstances of the explosion at a Lehi, Utah apartment complex were "considered suspicious," a city communications manager said.

The explosion caused damage inside the apartment and to the building's fire sprinkler system, leading to water damage in the apartment and some apartments below it.

An explosion injured two people and forced the evacuation of 90 families from a Lehi apartment complex Tuesday morning.

Lehi Police say that 90 families are out of their homes now following an explosion at an apartment building early Tuesday morning.
