A pensioner who preyed on young heroin addicts and trafficking them into prostitution is to have his prison sentence increased by two years, the Court of Appeal has ruled. Senior judges held that the seven-year term originally handed down to Oliver James MacCormack, 72, was unduly lenient. The former car salesman was told he must now serve nine years for a campaign of exploitation described as the most serious of its kind in Northern Ireland. Charles MacCreanor KC, for the PPS, argued that MacCormack manipulated and exploited young women who relied on him for heroin. Backing the PPS case, the three appeal judges formally declared that the sentence was unduly lenient.
