A humpback whale is now free in Unalaska after being tied up for at least four days. The entangled whale was first reported on Monday evening in Iliuliuk Bay.

Officials from the National Oceanic and Atmospheric Administration and the Alaska Department of Fish and Game were able to free the whale Friday morning. The team included Ed Lyman, a large whale entanglement response coordinator from Hawaii, and Sadie Wright, a biologist from Juneau. They both flew into Dutch Harbor Thursday morning and worked on detangling the whale until late Thursday afternoon. They resumed work the following morning at sunrise and freed the whale around 10 a.m. The whale swam out of the bay and into the Bering Sea.

Julie Fair, a spokesperson for NOAA, said additional information about the rescue will be provided later.

During the entanglement process, U.S. Coast Guard personnel were present on a nearby boat, and officials used a drone during the operation.
