An internal Google email reveals more evidence of the company's tip line for reporting whistle-blowers

A new filing in a lawsuit against Google shows evidence that the company's rumored team that tracks down employees who leak information does indeed exist.

The email comes from a lawsuit filed by an anonymous Google employee who claims the company runs a "spying program" that encourages employees to report each other for leaking information to the press or public, as The Information first reported in December. The lawsuit says the program violates California labor law.

According to the latest filing, the email was written by Brian Katz, who identifies himself as the leader of Google's "Investigations team," which includes the "stopleaks@" tip line that allegedly encourages Google employees to report leakers.

The email refers to an incident last year when a transcript from an internal all-hands "TGIF" meeting leaked to Recode. The email says the employees who leaked the transcript and memes were identified and fired and warns employees against leaking internal information to the press.

We've reached out to Google for comment on its investigations team.
