The group attempted to import almost £3 million worth of the class A drug concealed in their luggage on flights from Ghana to the UK.
Puplampu was in regular contact with compatriot Eric Appaih who tried to import 15 kilos of cocaine hidden in food boxes.
He was also connected to Albert Gyamfi and Jennifer Agyemang.
They had been stopped by Border Force officers on arrival at Heathrow earlier in 2021, with 15 kilos of cocaine hidden in a concealment in Agyemang’s suitcase – the same type of concealment used by Puplampu.
Home Office Immigration Enforcement International supported the investigation by providing evidence of links between the conspirators and their modus operandi and revoking visas to disrupt their activity.
This investigation has prevented an international cocaine smuggling group from getting their drugs to the UK market and seen the perpetrators given significant prison sentences.
