SEATTLE (AP) — What authorities describe as a homeless camp on the water has sunk.

KOMO-TV reports it may be a first for Seattle, a city plagued with homeless camps under highways, street corners, in greenbelts and abandoned buildings.

The floating camp was made up of three boats rafted together and tied up illegally to a fishing net piling belonging to the Duwamish Tribe.

Two boats sank last week in the Duwamish Waterway while a third boat remained afloat.

Officials say the Coast Guard pumped out fuel and removed hazardous chemicals that were found on board.

On Wednesday, a salvage crew removed both boats.
