Four men have been charged over an attempt to take control of computers at a bank branch to steal millions of pounds, Scotland Yard said.
Police thwarted the cyber gang after one of the plotters allegedly posed as an engineer to fit a computer in a branch of Santander with a "keyboard video mouse" device that allowed them to transmit its desktop contents.
It is alleged the gang tried to use the gadget to take control of all the computers at the branch in Surrey Quays shopping centre in south-east London, but the attempt failed and the Spanish bank said they were unable to steal any money.
Lanre Mullins-Abudu, 25, from Putney; south-west London, Dean Outram, 34, from north-west London, Akash Vaghela, 27, from Hounslow, west London, and Asad Ali Qureshi, 35, from south-west London, have been charged with conspiracy to steal.
They will appear at Westminster Magistrates Court today.
