A sixth person has been charged in connection with a south-west Sydney security business that allegedly acted as a front to launder $100 million from organised crime groups in Australia and abroad.

Assure Protection Services in Guildford was raided by the NSW Criminal Groups Squad in July last year, after an unrelated drug investigation uncovered an alleged money laundering syndicate.

Police allege the security firm was a semi-legitimate business servicing retail, industrial and commercial industries, however its primary function was to “act as a front” for the money laundering operation; taking cash, depositing it at local banks, withdrawing it and handing it back.

In July 2019, three people were arrested and charged, including the alleged ringleader Gagandeep Pahwa, 30, his domestic partner Gopali Dahl, 30, and their associate Bipin Thapa, 29.
