Victoria Police say 1000 files leaked The lives of informers and police officers have been put at risk over the "gravest" of leaks from inside the force. THE scale of leaked Victoria Police files is "enormous," with up to 10,000 pages of documents found at three Melbourne premises, Chief Commissioner Ken Lay says. About 1000 police files were found at the premises, which include one with direct links to bikies, he said. Mr Lay said the scale of the discovery was shocking for the organisation. The vast majority of people mentioned in the documents were people with long criminal histories and some had already been visited by police to ensure they are not hurt, he said. "The good thing about this is, every one of these documents, we can actually follow the order trail and understand when, how and who actually had access to them so that is of some comfort," Mr Lay told 3AW today. The overwhelming feeling in the organisation at the moment is that there has been a gross betrayal of the organisation, of the community and of the colleagues close to this person that has undertaken this act. Victoria Police Chief Commissioner Ken Lay reveals police information leak. He said there were two very high risk matters that police needed to get on top of very quickly and he believed they had done that. Leaks by cops put lives in danger "We just do what is called a risk assessment and we work our way through what the best way of keeping these people safe is," Mr Lay said. He said the documents were printouts from the LEAP database and other police systems and they went back nearly three years. The chief commissioner said the person should not have had access to the data, but used a method to access it that prevented people from knowing. "Obviously someone has taken a fairly proactive approach to collecting a whole host of data around particular people," Mr Lay said.

A junior officer at the centre of the leak scandal has been suspended without pay and is likely to be charged, police said on Monday. Mr Lay said on Monday the leaked documents put the lives of police and members of the public at risk.
