Four people are injured after an explosion at Oselka Marina.

The explosion happened Saturday afternoon around 5 when a boat was at the gas dock.

New Buffalo City's police chief said the explosion is believed to be caused by an issue with the boat's blower or another mechanical condition.

The chief said the fire put itself out and the New Buffalo Fire Department was able to control the fuel spill and attend to those injured.

Three people were transported to the hospital in an ambulance, while one person transported themselves in a personal vehicle; three were not seriously injured, but the fourth person's condition is not known at this time.
