A bikie informant inside the NSW Police Force has allegedly leaked sensitive information about several criminal investigations, risking the safety of undercover police agents.
Fairfax says the infiltration of state and federal drug inquiries by the Comanchero bikie gang has been described as one of the worst cases of alleged corruption in the NSW Police in recent years.
Officials suspect the leaked information includes intelligence gathered by Australia's elite crime fighting body, the Australian Crime Commission, the NSW Crime Commission and the NSW Police.
The information allegedly obtained by the bikies jeopardised the safety of undercover police operatives because it triggered suspicion in the gang about spying within its own ranks.
Fairfax says that late last year NSW Police anti-corruption investigators charged the suspected informant, the police analyst Terry Gregoriou, with stealing three police documents.
A joint investigation by Fairfax and the ABC TV's Four Corners into organised crime, to be aired on Monday, reveals that the alleged leaks occurred during one of Australia's most significant multi-agency criminal inquiries.
Law enforcement sources said they suspected that associates of the Comancheros actively cultivated Mr Gregoriou to work for them while he simultaneously worked for the police.
The Comancheros operate in Sydney, Perth and Melbourne, and some of the group's members are allegedly involved in organised crime activity, including drug trafficking and extortion.
Mr Gregoriou is suspended with pay from the NSW Police. He will appear in Downing Centre court on Monday.
