SEATTLE - Coast Guard crews and others quickly searched for a reported person overboard from the Washington state ferry Wenatchee.
The call, which proved to be a false alarm, came in at about 8:28 a.m.
Live cameras showed the ferry stopped in the water of Elliot Bay, just north of West Seattle.
At one point, the Coast Guard launched a helicopter and a fast boat to aid in the search.
Ferry passenger Ron Atherley said the ferry deployed a rescue boat.
"The (ferry) Bremerton came by as well to come look, so it seems like there was a few other boats that were called in," said Atherley.
According to the Guard, Wenatchee's captain determined that someone thought they saw a person in the water but it turned out to be a floating log with a balloon attached to it.
While Atherley was talking with KING 5 News via phone, the captain of the Wenatchee announced on the loudspeaker that the search was over.
"We completed a search of the area and we did not find anyone fallen overboard," he said. "We found a lot of debris that could have looked like a person in the water. With that information we are going to proceed into the dock once our rescue boat is safely on board and secure, and thank you for your patience."
