Operation Whistler was an investigation into the supply of huge quantities of Class A drugs – heroin and cocaine – and money laundering in Preston and the surrounding area.
The gang’s kingpin Niall McFarlane sourced the drugs wholesale which were then distributed to other members of the OCG who adulterated the product before selling it on to users through ‘drug lines’, phone numbers used to advertise drugs for sale.
