An over-excited 50 Cent fan got beat down after they ran on stage during a Fiddy concert.

He was left bloody by security after he tried to get near to the rapper at his concert at Wet N' Wild in Salvador, Brazil last Friday.

Check out the video of the incident as the dude tries to grab 50 Cent during his hit song "Ayo Technology".

50 Cent brushed off the incident and continued his set, but Lloyd Banks was keen to let in go and can be seen in the video throwing some licks...
