A 37-year-old Sun journalist has been released on bail following his arrest yesterday morning on suspicion of handling stolen goods.
The journalist, who has not been named, was bailed to return pending further inquiries in September.
His arrest came a day after a 51-year-old man, widely named as The Sun's chief foreign correspondent Nick Parker, was also arrested by officers from Operation Tuleta, the Met unit investigating criminal breaches of privacy.
The 37-year-old journalist is the ninth person arrested by Operation Tuleta, which is working alongside the Met's phone-hacking investigation, and the third journalist arrested on suspicion of handling stolen goods.
In a statement the Met said he was held in relation to a suspected conspiracy involving the gathering of data from stolen mobile phones.
A Scotland Yard spokesman added: "The arrest is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately."
