SAN FRANCISCO (AP) – The entire crew of the cargo ship that sideswiped a bridge, causing San Francisco Bay’s worst oil spill in nearly two decades, has been detained as part of a criminal investigation, a Coast Guard official said Sunday.

Capt. William Uberti said he notified the U.S. attorney’s office on Saturday about issues involving management and communication among members of the bridge crew: the helmsman, the watch officer, the ship’s master and the pilot.

The entire crew of the Cosco Busan, which disgorged 58,000 gallons of oil into the Bay on Wednesday, is being detained on the ship for questioning, said Uberti, head of the Coast Guard for Northern California.

Uberti declined to specify what problems he reported. A call to that office was not returned Sunday.
