Members of a drugs gang which distributed more than £20 million pounds worth of heroin have been jailed.
Murat Gungor, 36, of Ching Way, in Chingford, was convicted of two counts of conspiracy to supply heroin and sentenced to 15 years in jail.
Gungor was sentenced along with three other men at Wood Green Crown Court.
A Metropolitan police operation between March and November 2013 resulted in a total of 20 men and two women being arrested after the seizure of 100 kg of heroin worth £20 million and £1.1 million in cash.
Throughout the 8 month operation, police found a heroin lab in the basement of the tanning salon in south west London, a drugs production factory at a flat in Lewsham and two large suitcases stuffed with over £1 million pounds in cash.
Detective Inspector Chris Heerey, who headed up the investigation said: "These most recent sentences demonstrate that those who choose to deal in illegal drugs will feel the full force of the Met.
"This was a lengthy and complex investigation which has stopped huge quantities of potentially lethal drugs from making it onto the streets.
"Our message is clear: if you deal in drugs we will find you, we will arrest you and you will be put in front of the courts to face the consequences."
