Two Colombian drug barons who lived seemingly ordinary lives in London have received heavy jail sentences.
The pair, who entered Britain as asylum seekers in 1990, admitted conspiracy to supply drugs and money laundering.
Jesus Anibal Ruiz-Henao, 45, was sentenced to 19 years behind bars, while 32-year-old Mario Tascon received a 17-year jail term.
The pair ran a network worth nearly one and a half billion euros.
A London police spokeswoman explained: “They had set themselves up on business principles so they had very sedentary lifestyles.
“They were not visible to the community. They operated within the close confines of a family network or amongst close friends and relations.
“So the intelligence that was available to the police and the law enforcement forces was minimal”.
Ruiz and his brother-in-law Tascon ran a 50-strong gang whose trade was so important that the wholesale price of cocaine reportedly shot up by 50 per cent when their cartel was broken up.
A total of 32 other people have admitted or been found guilty under the investigation, which has only now been made public because of reporting restrictions.
