Aircraft
Shortly after departure; I was notified by the flight attendant that a leakage from the right wing was observed by one of the passengers. Upon a brief inspection from the cabin; I determined that we had a significant fuel leak. The leak appeared to be coming between the right aileron and the outboard portion of the wing.At that point; [ATC was advised] due to the fact I had no idea what the cause of the leak was. We turned around and landed uneventfully; where we were met by emergency personal.
GIV Captain reported returning to departure airport after a passenger noticed fluid leaking from the right wing.
