Two men have been arrested for suspected involvement in a nefarious phishing scam targeting the financial sector.
The Metropolitan Police Service confirmed arresting an unnamed 20-year-old man, from north London and a 23-year-old from Enfield on Thursday.
"The arrests are in connection with an operation investigating the distribution of stolen financial data obtained by means of organised international crime," read the Met Police's statement.
"In this case, the rogue phishing emails were designed to lure innocent victims into giving up their bank login details. These details have a black market value and can be resold or used directly to facilitate fraudulent transactions."
The arrests are the latest step in an ongoing joint operation between the Mets' Police Central eCrime Unit (PCeU) and the Serious Organised Crime Agency (SOCA) that has already seen two other men arrested for suspected involvement in the scam.
"The PCeU and SOCA are conducting joint operations in anticipation of the setting up of the National Cyber Crime Unit," the Met said.
"They are the third and fourth men to be arrested during this inquiry."
The National Cyber Crime Unit is a key part of the UK's Cyber Strategy and is set to fully launch later this year.
The strategy was announced in 2011 when the government pledged to invest £650m to help businesses combat the increased cyber threat they face.
The investment has funded several other initiatives outside of the National Cyber Crime Unit
Most recently it has seen the creation of a Cyber Security Information Sharing Partnership (CISP) and Global Centre for Cyber Security.
