Queensland Premier Campbell Newman and his wife Lisa. Mr Newman and his wife are understood to have received prank phone calls on Sunday, upsetting the family. The security breach was condemned by a spokesman for the Premier on Sunday night. "This breach of the Premier's privacy is concerning and regrettable," the spokesman said. "It is particularly distasteful given it involves the Premier's family."

The nature of the security breach was bought to the Premier's attention by Fairfax Media on Sunday. Fairfax Media understands the mobile phone numbers and address were copied by an employee at a Brisbane car dealership when the Newman family’s car was serviced in August. The employee posted the details on their personal Facebook page on August 15. Despite removing them soon after, the Premier’s personal details were shared with a social media site linked to motorcycle clubs. It is understood the employee at the car dealership wrote a letter of apology to the Premier, but was not sacked or reprimanded.

Comment is being sought from the car dealership. Police Minister Jack Dempsey said sharing Mr Newman’s details the second time constituted "disgusting, gutless attacks". "That particular matter came to our attention a couple of months ago," Mr Dempsey said Monday morning. "And certain actions have taken place." Meanwhile, police are investigating a YouTube video directed at the Premier purportedly posted by international cyber hacker group Anonymous.

The video, which criticises the government’s controversial new anti-association laws, has been viewed more than 100,000 times since it was posted last Thursday. The four-and-a-half minute clip ends with the words: “We do not forgive, we do not forget. Campbell Newman expect us.’’ However, the clip’s creator says the line is not a veiled threat to the Premier, but rather a twist on Anonymous’ famous sign off: “We do not forgive. We do not forget. Expect us”. ‘‘ ... they used our motto "expect us" and turned it into a threat ... ok, so what did i threaten to do? lol,’’ the creator’s unedited response on YouTube reads. ‘‘i [sic] have never hurt anyone nor has anyone i [sic] associate with, but, we are watching, and he can expect his lies to be made public.’’

The YouTube clip features an activist wearing a Guy Fawkes mask - the symbol of the Anonymous movement - speaking in a computerised voice. ‘‘There are cases where normal people on motorbikes have been harassed, searched and investigated for nothing more than riding a motorcycle,’’ the message says. ‘‘The bill has already been used against everyday people like you and me ...Campbell Newman has gone too far.’’ The footage used appears identical to that used in other YouTube videos posted by Anonymous activists in the US. Police are investigating the video but have refused to comment on the legitimacy of any threat.

‘‘The Queensland Police Service is aware of and investigating an online message from an anonymous source directed at the Premier of Queensland Campbell Newman,’’ police said in a statement. ‘‘As the matter is currently under investigation it would be inappropriate for us to comment any further.’’ Anonymous, a loosely associated international network of activists and hackers, is known for highly publicised cyber-attacks around the world since it was established in 2003. In 2012, Time magazine called Anonymous one of the "100 most influential people" in the world. Loading

Mr Dempsey said the " gutless" Anonymous video was already being investigated thoroughly by police. "They're just gutless cowards, They have to hide behind a mask."
