Two brothers who tried to flood the north-east of Scotland with heroin and cocaine have been jailed. Paul and Anthony Smith were jailed for more than five years each after they admitted transporting a "significant" amount of class-A drugs into Aberdeen and Shetland. The pair, originally from Liverpool, were sentenced at the High Court in Aberdeen on Monday after previously admitting being involved in the supply of heroin and cocaine between October 2010 and February last year. Detective Inspector Alex Dowall said: "These men were intent on flooding the streets of Aberdeen and Shetland with class-A drugs and were willing to take great risks in the process in order to turn a profit. "Ultimately though, as their sentences today prove, the risk is much greater than the potential reward." Anthony Smith, 30, was jailed for five years and seven months while his 27-year-old sibling received a sentence of five years and two months. Det Insp Dowall added: "This was a complex inquiry across two countries and three force areas and it should serve as a warning to others intent on bringing drugs into the north-east that it will not be tolerated. "Operation Limehouse is an example of Grampian Police working closely with other police forces across the UK in order to target those suspected of committing drugs offences. "It must also be said that the assistance provided by local communities in Aberdeen and Shetland in bring these individuals to justice was invaluable."
