By Phil Noble WITHERNSEA, England (Reuters) -British police arrested a man on Tuesday on suspicion of gross negligence manslaughter after an unexplained collision at sea left a tanker carrying U.S. army jet fuel with a gaping hole in its side and a container ship adrift and likely to sink.

"Both vessels are abandoned. Vessels with fire-fighting or rescue equipment should report to the Humber Coastguard. The 'Stena Immaculate' is carrying aircraft fuel, which is now burning and leaking into the water."

The captain arrested in a crash into a U.S.-flagged tanker off the coast of England is a Russian national, the owner of the vessel said.
