Jersey resident Taffin Carter, the pair drove around in Carter's VW Golf to various locations, including the isolated St Catherine's Breakwater. With drugs at three times the street price in Jersey compared with the UK or France, after Warren returned to the UK, Jersey Police created "Operation Koala," monitoring and bugging various locations, including phone boxes and the home of Taffin's girlfriend, Suzanne Scurr. From this they discovered that a friend of Warren, John Welsh, intended to travel to Amsterdam to meet with known Warren associate, Moroccan Mohammed Liazid. Jersey Police wanted to bug Welsh's hire car from St Malo, but were refused permission by French and Belgian police, saying it was a breach of the European Convention on Human Rights. In what Judge Sir Richard Tucker later described as a "reprehensible" and "unlawful" act, Jersey Police, which is not signed into but bound by the ECHR, bugged the car anyway, and with Dutch Police, SOCA and Interpol monitored the transmissions.

He pleaded not guilty, and there ensued a two-year legal argument over the legality of the information obtained by the bugging of Welsh's car. After agreement that there was sufficient evidence from other sources to substantiate the case, Jersey Police offered him a deal for pleading guilty of an 8-year jail term and no confiscation of assets: Warren turned this down. The Metropolitan Police agreed to lend Jersey Police a manned armoured prisoner transfer van, so Warren and his associates could be transferred safely during each day of the trial. The court heard that no drugs had been imported as the Jersey contacts had "failed to come up with the money". Senator Ben Shenton raised concerns that Warren's legal representation was at the cost of the Jersey taxpayer, while Progress
