LOS ANGELES -- The Coast Guard says a preliminary investigation finds faulty piping may have led to the leak of a large amount of oil in Los Angeles Harbor where cleanup efforts continue.
Petty Officer SondraKay Kneen says officials haven't determined how much oil leaked from the 577-foot car-carrying ship Istra Ace. The leak was stopped shortly after it was reported Sunday night.
Crews are on the scene again Tuesday, using boom, sweepers and absorbent pads to contain and clean up the oily mess.
The Coast Guard, the California Department of Fish and Wildlife, Los Angeles Port Police and fire officials are investigating.
