Police in Kentucky say two firefighters were seriously injured when the fire truck's ladder got too close to a power line as they helped college students take part in an ice bucket challenge.

Campbellsville Police Chief Tim Hazlette said Thursday that one of the firefighters is in critical condition and the other is stable. They were in the truck's bucket as it was being lowered when they were shocked.

He says two other firefighters on the main part of the truck were also shocked. They have been treated and released.

Campbellsville University asked the local fire department to help spray its Tiger marching band with cold water to raise awareness for ALS.

No students were hurt.
