As BP continues its work to permanently plug its blown-out well in the Gulf of Mexico, it is also busy investigating several hundred claims for compensation from those whose livelihoods have been affected by the oil spill.

The company has already paid out more than $300m (£191) from the $20bn (£12.7bn) fund put aside, but there are fears from Louisiana fishermen that some of this money is ending up in the wrong hands.

BP and the Louisiana Department of Wildlife and Fisheries have vowed to clamp down on fraudulent claims, as Robyn Bresnahan reports.
