Police held the 31-year-old man in a dawn raid on his home in Uxbridge, west London.
He was arrested on suspicion of corruption and conspiracy to cause misconduct in a public office and questioned at a west London police station.
The former NHS employee was the 36th person arrested under Operation Elveden, the Metropolitan Police's investigation into allegations that newspapers made illegal payments to police and other public officials.
Police said the arrest was prompted by information provided by News Corporation's management standards committee, which was set up in the wake of the phone-hacking scandal that led to the closure of the News of the World last July.
A Scotland Yard spokesman said: "Officers investigating allegations of inappropriate payments to police and public officials have arrested a man in Uxbridge this morning.
"The arrest was made at approximately 6am by officers from Operation Elveden, which is being supervised by the Independent Police Complaints Commission (IPCC) and is being run in conjunction with Operation Weeting, the MPS [Metropolitan Police Service] inquiry into the phone-hacking of voicemail boxes."
He added: "Today's arrest is the result of information provided to police by News Corporation's management standards committee.
"It relates to suspected payments to a public official and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately."
