Rap superstar 50 Cent had his diamond-encrusted chain stolen by an overzealous fan during a recent concert in the African country of Angola.
The 'In Da Club' singer, real name Curtis Jackson, was performing in Luanda with his G-Unit crew when one man jumped up onto the stage and grabbed the jewellery from his neck.
In grainy video footage posted online, the assailant can be seen running off with the chain as 50 Cent and his entourage chase after him.
According to TMZ.com, 50 Cent caught up with the thief and is alleged to have punched him before claiming back his prized chain.
A source tells the website: "The chain is around 50's neck right now."
