Liberia drops graft charges against ex-president's son

Liberia has dropped charges against four former central bank bosses, including an ex-president's son, in a highly publicised graft scandal over the mishandling of banknotes worth millions of dollars.

Five people were indicted last year for "economic sabotage" and other crimes after a probe found that an order for cash worth some 16 billion Liberian dollars ($80.6 million, 74.6 million euros) could not be traced.

Charles Sirleaf, the son of former Liberian president and Nobel laureate Ellen Johnson Sirleaf, was among the five originally indicted, as an ex-deputy governor at the central bank.
