The people smuggling kingpin behind the deaths of 39 Vietnamese migrants, remains at large, a judge has said, as police warned traffickers who trade in human misery “we will find you and we will stop you”. Four men were jailed at the Old Bailey on Friday for between 13-years and four months and 27-years after being convicted of the manslaughter of the migrants who suffocated in the back of a lorry in October 2019. But the judge in the case, Mr Justice Sweeney, said there was a mysterious Vietnamese mastermind by the name of Phong, who was at the very top of the conspiracy. Phong, who emerged as the mystery kingpin during the trial, took payments and organised safehouses across Europe for desperate migrants on their way to the UK. He is thought to have been operating out of a flat in south London and is still at large despite a major manhunt to track him down. The victims, Vietnamese men, women and children, had hoped for a better life in Britain when they agreed to pay up to £13,000 a head for a "VIP" smuggling service. On October 22 2019, they were crammed into a lorry container to be shipped from Zeebrugge to Purfleet in Essex in pitch black and sweltering conditions. But unable to raise the alarm they ran out of air before reaching British shores and suffered “excruciating deaths from asphyxia, carbon dioxide, poisoning” the judge said.
