Australian police's e-crime officers on Wednesday raided the office of a leading newspaper following allegations that it illegally accessed database of the ruling Labor party.

Six officers executed a warrant at the office of The Age newspaper this morning in relation to an investigation, media reports said.

Officers are also examining equipment in The Age's IT department.

"Victoria Police E-Crime Squad is investigating the allegation personal details of Victorians were electronically accessed by a media outlet via a confidential political party database without authorisation," a police spokeswoman said.

"As the investigation is active and ongoing we are not in a position to comment any further," she said.

Last year the newspaper had revealed that the Labor party had the personal details of thousands of Victorians in its database that was being accessed by campaign workers before the state election.

It is understood the warrants seek access to the computers and notes of a number of Age journalists.

Police are also seeking telephone records of several reporters over the four days leading up to the publication of the story last year.

It is understood police were seeking to identify which reporters accessed the Labor database from their computer terminals.

Police also want to try and identify the person who allegedly provided any reporter with the password to access the database.

"With Google and Clever Sense working together, our entire team looks forward to building more intelligent, serendipitous and magical services," he added.

In the first nine months of this year, Google completed the acquisition of 57 companies for a total of USD 502 million. This exceeds Google's previous annual record of 44 purchases, which was achieved last year. The company spent cash worth USD 669 million on acquisitions in 2010.

Google is estimated to have acquired over 100 firms in the past decade, translating into the purchase of 10 companies a year on average.
