(CAMPBELLSVILLE, Ky.) -- The popular ice bucket challenge has left four firefighters injured in Kentucky.
The marching band at Campbellsville University joined in on the ice bucket challenge, but instead of getting a bucket of water dumped on their heads, firefighters sprayed water on them from a ladder.
Police Chief Tim Hazlette says the ladder got too close to a power line and the electrical current injured four firefighters.
Two of the firefighters' injuries are serious.
The ice bucket challenge has spread across the country this summer as participants dump a bucket of ice water on their heads to raise awareness -- and donations -- for ALS.
