At 11:00am on March 12, Ms Dirksz tweeted: ‘Ben Cousins arrested after police pursuit. Charged with Reckless Driving, Fail to Stop and Failure to Provide a Sample of Breath.’ Mr Brown said Ms Dirksz had done nothing wrong but told 6PR Mornings radio Mr Jamieson’s alleged offences were an ‘absolute breach of trust not only for this agency but for the community at large’. Mr Jamieson will appear in Perth Magistrates Court on May 5. Daily Mail Australia has contacted Ms Dirksz for comment. Monique Dirksz got the scoop on Cousins' arrest. Officer Jamieson accused of divulging information that gave her a particular advantage . At 11:00am on March 12, Ms Dirksz tweeted: ‘Ben Cousins arrested after police pursuit. Charged with Reckless Driving, Fail to Stop and Failure to Provide a Sample of Breath.’ Acting Police Commissioner Steve Brown confirmed Ms Dirksz had done nothing wrong . Mr Brown is also concerned about the 112 police officers who had accessed Cousins’ confidential files 300 times in two days, some of whom were working in regional WA. ‘We want to know why they have accessed these records. It's a breach of trust,’ Mr Brown said. Officers also reportedly accessed files containing information about Daniel Kerr, a fellow former West Coast Eagles player, according to The West Australian. The pair both made headlines in recent months, for different incidents. Mr Brown confirmed to Daily Mail Australia an internal investigation is underway relating to access, but would not confirm or make comment about the people whose records had been accessed. Police in Western Australia have come under fire after reports emerged that hundreds of officers unlawfully accessed information relating to the arrests of fallen AFL star Ben Cousins (pictured on April 9) 'I can confirm that WA Police are currently investigating accesses, by a large number of police employees, to the records of high profile persons within our internal computer systems,' Commissioner Brown said in a statement. 'The focus of the investigation will be to determine if the accesses were justified having regard to the work role of each officer. This process will take some weeks, if not months, to complete. Allegations will be investigated under Section 440A of the Criminal Code, which states police officers face up to 12 months in prison or a $12,000 fine for unauthorised computer usage. 'The disappointing thing from my view is that the behaviour of these personnel has triggered a series of resource intensive internal investigations which will likely have criminal and/or internal disciplinary outcomes,' Mr Brown said. The disgraced football player (pictured during his career) was arrested three times in two weeks in March, and another warrant was issued for his arrest in April when he failed to front court . Cousins, pictured here in handcuffs arriving at court earlier in April, has a well-documented and public battle with methamphetamine . 'I suspect that the investigation will find that the majority of the accesses will have stemmed from mere curiosity, however this will not be known for sure until we undertake the investigation,' he added. In light of the incident the Acting Commissioner also assured West Australians that their information was safe. 'The community can rest assured that we hold their information in high regard and will conduct investigations into all suspected access breaches of our computer systems.' However the WA Police Union has reacted negatively to the news of an investigation, with president George Tilbury telling The West Australian officers had done nothing wrong. He said they exhibited 'professional curiosity' and added 'there is no suggestion in these cases of any corruption'. Ben Cousins was arrested three times in two weeks at the end of March, following a slew of erratic events . Cousins was spotted climbing onto the roof of a two-storey home in Perth earlier this month . Footage also emerged showing Cousins running through the streets away from police . Cousins was arrested three times in two weeks at the end of March, following a slew of erratic events. Cousins was reportedly arrested compulsively taking photos of a Sikh temple before climbing onto the roof of another home in Canning Vale in Perth's south. The 36-year-old footballer allegedly upset Sikh priest, Jasvinder Singh and his wife when he reversed his car over the garden of the temple ground and parked in Mr Singh's personal car park. On March 16 Cousins, who has a history of serious drug abuse, was assessed at a mental health facility after he was caught behind the secure fences of an SAS base. On April 8, when Cousins failed to front court on the driving charges a warrant for his arrest was issued. The next day the Perth-based former AFL star surrendered himself at Fremantle Police Station. Sorry we are not currently accepting comments on this article.
