Niall was a drug dealer who supplied Ryan Connor with cocaine. He met up with Niall in a ginnel where he brought some drugs before going to a gig. Several days later, Niall turned up at the Street Cars cab office where Ryan worked, asking for a discount cab claiming he had "packages to drop". Ryan told him to clear off but Niall tried to tempt him with some drugs. The conversation was interrupted by the arrival of Ryan's mother Michelle and Steve McDonald, the latter throwing Niall out. Actor Greg Kelly also played a drug dealer called Ricky in December 2007.
