Authorities say the green water flowing in the Ketchikan Creek that caused some panic and drew a response from multiple agencies was the result of a prank.

Officials have determined that the dye dumped into the water on Wednesday is non-toxic. Ketchikan police talked to the man responsible for the dye, but he was not arrested or cited.

“It was just a prank,” Officer Charles Johnson told The Ketchikan Daily News. “He happened to come across some sort of plumbing dye that they use for testing — checking for leaks and stuff — and thought it’d be funny to throw it in the creek and make people wonder why the creek was green.” (Read more from “Man Causes Panic After Dumping Non-Toxic Green Dye in Alaska Creek” HERE)
