THE union boss Michael Williamson has allegedly been caught attempting to take a bag of documents out of the HSU while a police raid occurs on the premises.

Detectives from Strike Force Carnarvon moved in this morning to raid the premises as part of their investigation into alleged corruption in the Health Services Union.



The head of the fraud squad, Detective Superintendent Colin Dyson, confirmed police were considering charging someone with attempting to hinder the investigation by removing information.



The Daily Telegraph reported that the person is Mr Williamson. The documents he attempted to remove were seized by police. Mr Williamson is also a former National President of the Australian Labor Party.



"One has major concerns that efforts have been made to interfere with information relevant to our investigation,” Mr Dyson said.



"I don't dismiss the possibility of criminal charges arising from those efforts.

"A bag of documents was intercepted this morning."



Mr Dyson confirmed the investigation went back to the mid 1990s and said the raid marked one of the "final steps" in the investigation.



Mr Dyson said if charges were laid over the incident this morning, this would occur in the "relative near future".



Police raided the HSU offices as part of their investigation into Williamson and Federal MP Craig Thomson.



The detectives entered just before 9am.



They were investigating claims Mr Williamson and Mr Thomson received American Express cards as a secret commission from a printing firm ‘Communigraphix.’



They were also investigating claims union architects carried out works on Mr Williamson’s home and that Mr Williamson’s computing firm received generous contracts from the union.



Mr Williamson and Mr Thomson deny any wrongdoing.

The raids came three days after Thomson, who is facing allegations relating to his time as HSU national secretary, resigned from the ALP.



The raids this morning follow previous raids on the home of Communiraphix owner, John Gilliland.

The union's national secretary Kathy Jackson, who went to police in September with allegations of corruption within HSU East, said the raid was overdue.



Police would uncover evidence that union executives were running their own fiefdom, she told reporters today.



"I have no doubt that the police will uncover documents that will prove that," she said.
