British Transport Police (BTP) discovered that Nawid Moshfiq was the ringleader of the gang which included Olia Moshiq, Paramijit Singh Kalra, 42, Harmet Bhatia, 24, Pritbal Bhatia, 55, Nirmohan Bhatia, 20, Ranjit Banger, 31, Mubarak Korasi, 41, Ahmed Raza, 28, Ariji Singh Sethi, 43, and Nirmohan Singh, 38.
More than 100 officers raided private properties and businesses in south-west London where more than a thousand smartphones and 143,000 pounds were seized as part of BTP's Operation Park.
"This was a long and complex investigation into a highly organised criminal gang who used stolen property from the rail network for their personal gain," said BTP Detective Chief Inspector John Justice.
"To truly tackle theft, we can't just catch pickpockets and petty thieves; we have to also dismantle the criminal networks behind them, who profit from this type of crime. Phones are often stolen out of view of CCTV in crowded carriages or busy stations without the owner even realising.
The court heard how the gang worked strict "office hours" between 2pm and 10pm, earning almost 10,000 pounds a day nabbing mobile phones from commuters on the London Underground, known as Tube.
At one address, officers seized more than 23,000 pounds which had been hidden in different rooms of the house, including inside a child's jacket.
