Bainbridge officials are asking residents who live along the shoreline of Eagle Harbor to “shelter in place and avoid windows.”

The warning came nearly an hour after authorities warned Bainbridge Island residents of an “active shooter” situation in Eagle Harbor.

Officials said a person on a boat started firing a gun Saturday sometime around 9 p.m., and that the gunfire was directed at the shoreline and later, officers who responded to the scene.

The person aboard the boat was believed to be on a boat near Washington State Ferries’ vessel repair yard at the eastern end of the harbor, adjacent to the Bainbridge Island Ferry Terminal.

The shooting was reportedly random, according to those who had heard the sporadic gunfire.

Roughly a dozen bystanders were spirited away from the city dock in Waterfront Park by emergency responders after the shooting began.

Multiple law enforcement agencies have been called in to assist the Bainbridge Island Police Department. An intermittent stream of sirens could be heard heading south on Highway 305 after 9:30 p.m.

Washington State Ferries suspended ferry sailings from Seattle to Bainbridge into Eagle Harbor just before 9 p.m.

Islanders on social media have reported hearing gunfire in the harbor, and some have said they thought it was fireworks.

Wrote one boater: “We docked our boat just before this started — went right past him. YIKES.”
