A man has been arrested in the African country of Angola on suspicion of stealing a diamond-encrusted chain from rap star 50 Cent.

Bruno Carvalho has been accused of jumping on the stage as the In Da Club hitmaker, real name Curtis Jackson, was performing in Luanda with his G-Unit crew.

According to The Angola Press, Carvalho's parents handed him over to the police after they identified him in grainy video footage posted online.
