Nollywood actress Uche Jombo has hit out at illegal downloaders, telling her followers on Instagram that it is a "sin against God".

''The thunder that will fire you... is still doing press up,'' the Damage star added.

As of the last count in 2016, Nollywood is a $658m (506m) industry which accounts for 2.3% of GDP, according to global accountancy firm PWC.

But the market for pirated copies and illegal downloads is booming, making it difficult to determine exactly what proportion of the music and films that people buy is the real deal.
