Coast Guard investigates second oil sheen in Gulf

GULF OF MEXICO (WAFB) - The US Coast Guard said it is investigating another oil sheen in the Gulf of Mexico.

This is the second sheen to appear near the site of BP's Deepwater Horizon disaster.

It is in the same area where an abandoned piece of equipment was blamed for leaving a sheen of oil weeks ago.

The Coast Guard said it will inspect the oil rig's wreckage with robots to find the source.
