Anas Aremeyaw Anas, one of Africa’s most intrepid undercover journalists, has a range of tools he uses when he tries to expose corruption.

He owns an array of wigs, prosthetic masks and tiny cameras; once he feigned madness to infiltrate Ghana’s largest psychiatric hospital; and he has posed as characters ranging from street hawkers to an albino body parts trafficker. He has even dressed up as a rock to film cocoa smugglers along Ghana’s western border.

But Anas’s best disguise is his simplest: he plays himself.

The whistleblower’s “name, shame and jail” mantra has made him an underground hero but equally earned him powerful enemies, so he keeps his real identity secret. You’d be hard-pressed to find a photo of his face online, and the beaded masks he wears in public periodically spawn Twitter contests as to who can pull off the best “Anas look”.

He was wearing this mask when he turned up under heavy police protection at Ghana’s judicial council this month to answer a summons from the country’s top judge, Georgina Wood. Ironically, it was hundreds of hours – disguise-free – prowling the court’s corridors that led to the summons.

Anas had been working on a documentary featuring secretly filmed footage of 34 judges taking bribes. For two years he pretended to be a relative or friend of an accused, offering to pay judges in exchange for passing shorter sentences. Twelve high court judges and 22 lower court justices were filmed accepting money – and in one case, a goat.
