The Charleston County Sheriff's Office is the latest public agency to accept the ALS Ice Bucket Challenge.

North Charleston Police Chief Eddie Driggers and several other officers poured buckets of ice water over the heads of four Charleston County Sheriff's Office supervisors on a sweltering Friday afternoon outside the Charleston County jail.

Driggers got drenched last week.

"It was a shock at first, and then it felt pretty refreshing," Maj. Eric Watson said.

Chief Deputy John Clark, Assistant Sheriff Mitch Lucas and Chief Deputy Willis Beatty also get drenched.

The Ice Bucket Challenge has gone viral in the last several weeks. The challenge had raised $62.5 million for the ALS Association as of Saturday, up from $53 million Friday, according to a news release on the association's website.

ALS - amyotrophic lateral sclerosis - is a progressive neural disease that leads to loss of movement. The theoretical physicist Stephen Hawking is the most famous living example. ALS is also called Lou Gehrig's disease, after the baseball player who succumbed to it in 1947.
