Alleged instances of computer-hacking will now be assessed by police alongside the ongoing phone-hacking investigation.
Operation Tuleta will take place while Operation Weeting continues, allowing police to look into claims that Trojan emails were used to extract information from individuals.
"Operation Tuleta is currently considering a number of allegations regarding breach of privacy, received by MPS [the Metropolitan police] since January 2011, which fall outside the remit of Operation Weeting, including computer hacking," a spokesperson from Scotland Yard said.
"Some aspects of this operation will move forward to a formal investigation. There will be a new team reporting to DAC Sue Akers [lead on Operation Weeting]. The formation of that team is yet to take place."
The decision to expand the investigation means three police inquiries are now taking place at once. The third, Operation Elveden, is currently looking into payments to the police from journalists in return for information.
Trojan emails infect a recipient's computer with a virus that can give the hacker remote access to files.
